E12038 — retired
The Bird API no longer returns E12038. If you reached this page from an older stored or logged response, that reference is still valid: error codes are never renamed or reused, so E12038 still identifies the failure your record captured.
If your integration still handles E12038, you can safely remove that handling: the API no longer produces it. A request that once failed this way either succeeds now or reports a different code, and the response tells you which.
