E12037 — retired

The Bird API no longer returns E12037. 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 E12037 still identifies the failure your record captured.

If your integration still handles E12037, you can safely remove that handling. Requests that used to fail with this code now return a different one, and that code's own page describes what to do.
