Error message
No height provided
What it means
filterFile() throws this at process.js:1377 when image is true, the upload is not an avatar, and req.body.height is falsy. Identical rationale to the width check (1373): height is recorded on the file and used by the image pipeline. Reached only when width already passed, so a missing height on an otherwise complete image upload is the trigger.

Solutions
- Append a positive integer height alongside width to the upload body.
- Use a single helper that sets both dimensions from naturalWidth/naturalHeight together.
- Guard the FormData construction so width and height are set atomically.
Example fix
// before
form.append('width', String(w));
// after
form.append('width', String(w));
form.append('height', String(h)); Defensive patterns
Strategy: validation
Validate before calling
function withImageDims(form, width, height) {
if (!(width > 0) || !(height > 0)) throw new Error('image dims required');
form.append('width', String(width));
form.append('height', String(height));
return form;
} Type guard
const hasPositiveHeight = (body) => Number.isFinite(+body?.height) && +body.height > 0;
Prevention
- Always append width and height in the same code block.
- Unit-test the FormData builder to assert both fields are present.
When it happens
Trigger: POST /api/files/images whose body omits height, sends height:0, or sends it under a wrong key. Fires immediately after the width check succeeds.
Common situations: Client builds FormData in a branch that sets width but skips height. Image with height 0 due to a failed dimension read. Copy/paste from a sample that only included width.
