Describe the problem/error/question
I am currently working on RAG-pipeline for my AI-agent, using Qdrant vector store and Cohere for reranking chunks. Everything worked well until Cohere reranker started returning 403-error. I do not understand: is this an api-usage issue or data which stored in my Qsrant vector store issue?
Error output:
ForbiddenError Status code: 403 Body: { "ok": false, "error": { "reason": "non-json", "statusCode": 403, "rawBody": "<!doctype html><meta charset=\"utf-8\"><meta name=viewport content=\"width=device-width, initial-scale=1\"><title>403</title>403 Forbidden" } }
But when I check this API-key on Cohere website, it works well:
Details: my n8n is self-hosted on VPS, using Docker.
What is the error message (if any)?
Error output:
ForbiddenError Status code: 403 Body: { "ok": false, "error": { "reason": "non-json", "statusCode": 403, "rawBody": "<!doctype html><meta charset=\"utf-8\"><meta name=viewport content=\"width=device-width, initial-scale=1\"><title>403</title>403 Forbidden" } }
**
Error occurs when I try to enter api-token in "Credential" page:**
Couldn’t connect with these settings
Forbidden - perhaps check your credentials?
