Frequently Asked Questions

CORS Issues

Problem: Requests to UiPath APIs may be blocked by CORS — both during local development and from deployed app domains.

Solution: Use https://api.uipath.com as the baseUrl in your uipath.json.

{
  "baseUrl": "https://api.uipath.com"
}

Authentication Errors

Problem: During authentication, you may encounter errors related to invalid redirect URIs, scopes, or other configuration issues.

Error URL Example: 

https://cloud.uipath.com/identity_/web/?errorCode=invalid_request&errorId=eyJDcmWRpcmVjdFVyaSI6bnVsbCwiUmVzcG9uc2VNb2RlIjpudWxsLCJDbGllbnRJZCI6IjhmZjMyM2FlLTAwZTEtNDU2NC1hOGMyLWVmZDg0YWY2Njc1MiJ9fQ

Solution: 1. Extract the Error Details: - Copy the errorId value from the URL (the long encoded string after errorId=) - Go to jwt.io - Paste the errorId value into the "Encoded" section - The decoded payload will show you the specific error details

  1. Example Decoded Error:
