Describe the problem/error/question
I am getting sporadic errors for my Webhook Node: Error: ENOENT: no such file or directory.
Data is sent from a Symfony Http Client 5.x (https://symfony.com). The caveat with this library is, that normal fields (non-files) are sent with text/plain content type in the form-data. This causes n8n (formidable) to interpret the fields as files (ContentType: text/plain not showing in fields · Issue #875 · node-formidable/formidable · GitHub). Since n8n 1.0 the formidable package was updated and the webhook behaviour for files.
We tried to solve this problem by checking if the file has a filename, if not, extract the contents as a JSON field. However, sometimes n8n is unable to save all the files. I tried to to change N8N_DEFAULT_BINARY_DATA_MODE, but the error occurs with both default and filesystem. I am not sure if this error is caused by too many files being saved in general (about 25 files) or with the “incorrect” content-type for normal text fields. The former sounds more plausible, because the error occurs sporadic. The same also happens with a custom node I used.
Is there any other n8n configuration I could try to solve this issue?
This thread has a similar issue Webhook node ERROR: ENOENT: no such file or directory, open '/tmp/12c77b592ffcb06bdd075cc07' - #3 by Jayavel.
What is the error message (if any)?
