Unable to upload file to Supabase storage bucket

I am unable to upload the n8n Binary file to Supabase storage bucket.

I have a PDF file that I have a generated thought an external API, and then have read that as a n8n Binary file. I am calling supabase api to upload the PDF in supabase bucket, I am using the following API.
https://[database-name].supabase.co/storage/v1/object/upload/sign/[Bucket-name]/testO

I need assistance to figure out the way to upload the binary file in the bucket and getting the signed URL as response.

It looks like your topic is missing some important information. Could you provide the following if applicable.

  • n8n version:
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

Hi @rafay_javed, I am sorry you’re having trouble.

I had a go at this and was able to upload a file like so (where https://lvuzqwrpevgqdinysmpj.supabase.co is my Supabase URL):

This returns a body.signedURL field with the signed URL path (which would go after the base URL):

Is this what you had in mind?
