http_cred '{}': header value is empty

Error message

http_cred '{}': header value is empty

What it means

Materializing the HTTP credential to a header pair yielded an empty header value. For the Header scheme this means the computed value from the stored secret is empty (trimmed to nothing); the guard in `to_header()` blocks injecting an empty header onto the outbound request.

Solutions

1. Update the credential so its secret is non-empty after trimming
2. For Header scheme, verify both header_name and secret are set
3. Re-save the credential from its original source
