Error Diagnosis Flowchart

ERROR IN CLIENT SCRIPT
│
├─► TypeError: Cannot read properties of undefined
│   ├─► "frm.doc.fieldname" → Field does not exist on DocType
│   ├─► "r.message.value" → Server returned null/error
│   └─► "row.fieldname" in child table → Row not fetched correctly
│
├─► frappe.call fails silently
│   ├─► Missing error callback → Add error handler
│   ├─► 403 Forbidden → Method not whitelisted (@frappe.whitelist)
│   ├─► 417 Expectation Failed → Server-side frappe.throw()
│   └─► 401 Unauthorized → Session expired or CSRF token invalid
│
├─► Uncaught (in promise) → Missing try/catch on async frappe.call
│
├─► Field appears blank after set_value → Timing issue (setup vs refresh)
│
├─► cur_frm is undefined → Using cur_frm in list/report context
│
└─► frappe.throw() does not prevent save → Used outside validate event

Error Message → Cause → Fix Table

Error Message	Cause	Fix
`TypeError: Cannot read properties of undefined (reading 'fieldname')`	Field does not exist on DocType or doc not loaded	ALWAYS check `frm.doc` exists before accessing fields
`TypeError: frm.set_value is not a function`	Using `cur_frm` shortcut that is undefined	ALWAYS use the `frm` parameter from event handler
`Uncaught (in promise)`	Unhandled async rejection from frappe.call	ALWAYS wrap async calls in try/catch
`CSRFTokenError` / `403 with CSRF`	Token mismatch after session timeout	ALWAYS use `frappe.call()` (handles CSRF automatically)
`Not permitted` / 403 on frappe.call	Server method missing `@frappe.whitelist()`	ALWAYS add `@frappe.whitelist()` decorator to API methods
`frappe.throw() not preventing save`	`frappe.throw()` used outside `validate` event	ALWAYS use `frappe.throw()` only in `validate`
`field not found: xyz` in set_query	Fieldname typo or field not in child table	Verify exact fieldname against DocType definition
`row.item_code is undefined`	Accessing child row wrong — `locals` not synced	Use `frappe.get_doc(cdt, cdn)` in child table events
`frm.set_value not working`	Called in `setup` before form fully loaded	Move field-setting logic to `refresh` event
`Maximum call stack exceeded`	Circular trigger — field change fires own handler	Use `frm.flags` guard to break recursion

Critical Error Patterns

1. cur_frm vs frm: The #1 Beginner Mistake

// ❌ WRONG — cur_frm is undefined in many contexts
frappe.ui.form.on('Sales Order', {
    customer(frm) {
        cur_frm.set_value('territory', 'Default');  // BREAKS in list view
    }
});

// ✅ CORRECT — ALWAYS use the frm parameter
frappe.ui.form.on('Sales Order', {
    customer(frm) {
        frm.set_value('territory', 'Default');
    }
});

Rule: NEVER use cur_frm. ALWAYS use the frm parameter passed to every event handler.

2. Async/Await: Silent Failure Without try/catch

// ❌ WRONG — Unhandled rejection crashes silently
frappe.ui.form.on('Sales Order', {
    async customer(frm) {
        let r = await frappe.call({
            method: 'myapp.api.get_data',
            args: { customer: frm.doc.customer }
        });
        frm.set_value('credit_limit', r.message.limit);  // r.message may be null
    }
});

// ✅ CORRECT — try/catch with null check
frappe.ui.form.on('Sales Order', {
    async customer(frm) {
        if (!frm.doc.customer) return;
        try {
            let r = await frappe.call({
                method: 'myapp.api.get_data',
                args: { customer: frm.doc.customer }
            });
            if (r.message) {
                frm.set_value('credit_limit', r.message.limit || 0);
            }
        } catch (error) {
            console.error('Customer fetch failed:', error);
            frappe.show_alert({
                message: __('Could not load customer details'),
                indicator: 'red'
            }, 5);
        }
    }
});

3. Child Table Access: Wrong Pattern

// ❌ WRONG — frm.doc.items[0] may not reflect latest state
frappe.ui.form.on('Sales Order Item', {
    item_code(frm, cdt, cdn) {
        let row = frm.doc.items.find(r => r.name === cdn);  // fragile
        row.rate = 100;  // Does not trigger UI refresh
    }
});

// ✅ CORRECT — Use frappe.get_doc and frappe.model.set_value
frappe.ui.form.on('Sales Order Item', {
    item_code(frm, cdt, cdn) {
        let row = frappe.get_doc(cdt, cdn);
        if (!row.item_code) return;
        frappe.model.set_value(cdt, cdn, 'rate', 100);  // Triggers refresh
    }
});

4. Timing: setup vs refresh

// ❌ WRONG — set_value in setup, form not ready
frappe.ui.form.on('Sales Order', {
    setup(frm) {
        frm.set_value('company', 'My Company');  // May not work
    }
});

// ✅ CORRECT — set_query in setup, set_value in refresh/onload
frappe.ui.form.on('Sales Order', {
    setup(frm) {
        // Filters belong in setup
        frm.set_query('customer', () => ({ filters: { disabled: 0 } }));
    },
    refresh(frm) {
        // Value changes belong in refresh (or onload for new docs)
        if (frm.is_new()) {
            frm.set_value('company', 'My Company');
        }
    }
});

5. frappe.throw() Scope: Only Works in validate

// ❌ WRONG — throw in customer change does NOT prevent save
frappe.ui.form.on('Sales Order', {
    customer(frm) {
        if (!frm.doc.customer) {
            frappe.throw(__('Customer required'));  // Stops script, NOT save
        }
    }
});

// ✅ CORRECT — throw in validate prevents save
frappe.ui.form.on('Sales Order', {
    customer(frm) {
        if (!frm.doc.customer) {
            frappe.msgprint({ message: __('Customer required'), indicator: 'orange' });
        }
    },
    validate(frm) {
        if (!frm.doc.customer) {
            frappe.throw(__('Customer is required'));  // Prevents save
        }
    }
});

6. Recursion Guard with Flags

// ❌ WRONG — discount change triggers amount recalc, which triggers discount...
frappe.ui.form.on('Sales Order', {
    discount_percent(frm) {
        frm.set_value('grand_total', calculate(frm));  // Fires on_change loop
    }
});

// ✅ CORRECT — Use flags to break the cycle
frappe.ui.form.on('Sales Order', {
    discount_percent(frm) {
        if (frm.flags.skip_recalc) return;
        frm.flags.skip_recalc = true;
        frm.set_value('grand_total', calculate(frm));
        frm.flags.skip_recalc = false;
    }
});

Debug Tools

Tool	How to Use	When
Browser Console (F12)	`console.log(frm.doc)`	Inspect form state
`console.table()`	`console.table(frm.doc.items)`	View child table rows
`JSON.parse(JSON.stringify(frm.doc))`	Deep-clone for snapshot	Avoid circular refs in console
`frappe.boot.developer_mode`	Check if dev mode on	Conditional debug logging
`frappe.ui.toolbar.clear_cache()`	Clear client cache	After deploying script changes
Network tab (F12)	Filter XHR requests	Inspect frappe.call payloads
`frappe.show_alert({message: 'debug', indicator: 'blue'}, 5)`	Visual debug in UI	Quick feedback without console

ALWAYS / NEVER Rules

ALWAYS

Use the frm parameter — NEVER use cur_frm [v14+]
Wrap async frappe.call in try/catch — Unhandled rejections fail silently
Use __() for all user-facing strings — Required for translation
Collect multiple validation errors before calling frappe.throw()
Use frappe.get_doc(cdt, cdn) to access child table rows in events
Put frappe.throw() only in validate to prevent save
Check r.message for null before accessing server response properties
Use frappe.model.set_value(cdt, cdn, field, value) in child table events

NEVER

NEVER use alert(), confirm(), or prompt() — Use frappe.msgprint / frappe.confirm
NEVER expose stack traces to users — Log to console, show friendly message
NEVER use cur_frm — It is unreliable and undefined in many contexts
NEVER leave console.log in production — Use conditional frappe.boot.developer_mode check
NEVER mix .then() and await in the same function — Pick one pattern
NEVER call frm.set_value in setup — Form is not ready; use refresh or onload
NEVER ignore the error callback on frappe.call when using callback style

});

// ✅ CORRECT — try/catch with null check

        if (!frm.doc.customer) return;
        try {
            let r = await frappe.call({
