failed to extract secret: %w

Error message

failed to extract secret: %w

What it means

After a 200 response, extracting the secret from the body failed — reading the body or resolving the configured responsePath. The extraction step wraps its own error; see the cause for whether it was a read or path problem.

Solutions

1. Check the wrapped error: 'path not found' means the responsePath doesn't match the JSON; read errors mean connection issues
2. Verify responsePath (a gjson path) against the actual service response
3. Omit responsePath if the whole body is the secret
