Google Vertex LLM does not work with Agent AI

Igor_Santos · August 15, 2024, 3:51pm

When entering the credentials to use Google Vertex with the Agent AI - Tools Agent node, and even after validating the credentials, an error appears:

### Bug Description I am unable to interact with any Google Cloud service that …uses a service account. I have tried with BigQuery and Vertex AI so far. The error in the console shows the error: call to gauth.request message: error:1E08010C:DECODER routines::unsupported ### To Reproduce 1. Create a BigQuery Node. 2. Create or attach a Service Account to the BigQuery Node. 3. Insert a Project ID and a query in the respective fields. 4. Run the workflow with a "click" trigger. ### Expected behavior The BigQuery Node should run successfully and return results. ### Operating System Docker ### n8n Version 1.53.2 ### Node.js Version 20 ### Database PostgreSQL ### Execution mode main (default)

Having this too.

SOLUTION is here error:1E08010C:DECODER routines::unsupported when using Google Cloud Service Account · Issue #10347 · n8n-io/n8n · GitHub

This is a problem related to new lines inside the key. I managed to fix the error by switching the key format input type to “expression”
