Log Type: APPLICATION

## Description

Twilio Verify could not generate a message from the provided templates. This occurs when all supplied template candidates fail validation, such as when a template is unapproved or missing required substitutions

HTTP status: 400

### Possible causes

* One or more template candidates are unapproved
* One or more candidates are missing required substitutions.
* A template candidate does not support the requested delivery channel.
* A template candidate contains invalid content for its template type.

### Possible solutions

* Review each template candidate to confirm that it is approved.
* Provide all required substitution values for every template candidate.
* Use only template candidates compatible with the requested delivery channel.
