Failed to Add Data Source: 401 Authorization Error

Error Message​

Error code: 401
{
  "error": "missing authorization",
  "message": "Authorization header is required"
}

Cause​

Missing Compute API KEY (LLM_API_KEY), which prevents the system from calling the large model to analyze the data source.

Solution Steps​

1. Obtain the Compute API KEY​

Log in to AskTable SaaS Platform → Top-right avatar → AI Compute → Request Token

Enter AI Compute Page
Get Compute API KEY

Format: asktable-xxxxxxxxxx...

2. Configure on Local Deployment​

Refer to Model Group Configuration Guide to configure the LLM_API_KEY on your local instance.

3. Restart Service and Verify​

Restart the AskTable service, re-add the data source, and confirm there is no 401 error.

Frequently Asked Questions​

Still getting an error after configuring the API_KEY?

API_KEY and LLM_API_KEY are two different keys:

  • API_KEY: Used to call the AskTable backend API
  • LLM_API_KEY: Used to call the large model service (required for adding a data source)

Still getting an error after configuration?

Check:

  • Correct format (starts with asktable-)
  • The key is not expired and has sufficient quota
  • No extra spaces or line breaks in the configuration file
  • The service has been restarted

Can I use a local model?

Yes, refer to Model Group Configuration Guide to configure a local model.
