n8n integration

Hello,

I am having a persistent authorization issue while trying to connect to the Invoice OCR API from my n8n.cloud workflow.

I have already:

1. Confirmed that the "Invoice OCR" model is active in my Mindee dashboard.

2. Generated a brand new, clean API key from the "API keys" section of my account.

3. Copied this new API key and created a new credential in the official Mindee node in n8n. The node is configured correctly to predict an invoice from a binary file (attachment_0 from a Gmail trigger).

Despite these steps, I consistently receive a 401 Unauthorized error with the message "Invalid token provided" every time I execute the node. I have tried generating multiple new keys, and the result is always the same.
