Email template not updating

This is a copy of a troubleshooting article on Supabase's docs site. It may be missing some details from the original. View the original article.

If your email templates are not updated, check Auth Logs for any errors when the email is sent. When there are errors, we will use a fallback template with valid syntax so it will not show any of your customizations.

Typical errors relate to invalid syntax involving variables. Refer to the Email Templates docs for the supported variables and syntax.

Example error message

"event": "templatemailer_template_body_parse_error",
"msg": "templatemailer: template type \"recovery\": template: https://api.supabase.com/platform/auth/PROJECT_ID/templates/recovery:2: function \"default\" not defined",

The error shows an issue with default which is used in the invalid syntax below.

{{ .Data.display_name | default: "test" }}

The final correct syntax after removing invalid syntax.

{{ .Data.display_name }}
