Just replace the item_id and column_id as needed. The request returns the ID of the uploaded file (I think) and the file shows up in Monday as expected:
Hi @pedrofnts, I am so sorry. Are you also seeing this problem when using my test workflow (with updated IDs of course, but otherwise unchanged)?
If so, can you confirm the details requested in the question template here on the forum? I’d especially like to understand which version of n8n you are currently running and how you have it deployed. The value of the N8N_DEFAULT_BINARY_DATA_MODE environment variable would be interesting as well to see here.
