email.template_render_failed
Recorded as an outbox message's lastErrorCode, not returned by an endpoint: the template did not render when the message was composed, so the row was written Failed without bodies.
| Code | email.template_render_failed |
|---|---|
| HTTP status | None: a result code, recorded on a resource (for example an operation's resultCode) rather than returned as a problem response (— (result code)) |
| Arguments | None (args is {}) |
Handling it
Branch on code, not on title or the status alone, and log traceId. Codes are stable; new codes may appear, so fall back on the HTTP status for a code you do not know. See Handling errors and the list of codes.
