Hello,

I integrated the Anthropic pipeline available at this link: https://github.com/open-webui/pipelines/blob/main/examples/pipelines/providers/anthropic_manifold_pipeline.py to test its capabilities. I retrieved the API, but I get this error message when attempting to communicate with the AI Claude 3-5:

Error: Error code: 401 - {type: error, error: {type: authentication_error, message: invalid x-api-key}}

Note: The API key is valid.

Please help

you can either start the Pipelines Docker container with environment variable -e ANTHROPIC_API_KEY=your-api-key or set it in Admin Settings > Pipelines Anthropic valves configuration:

Well, the problem came from my API key, I think there are issues on Anthropic's side, thank you for your help.
