90025: Template body has unsupported tag type

This error occurs when your template body includes a Mustache tag type that Twilio does not support. Use only data tags in {{}} for placeholders, such as {{1}} or {{CustomerName}}.

• The template body includes a Mustache tag or command other than a data tag.
• The body mixes supported placeholder tags with other Mustache commands.
• The body uses syntax that is not a simple placeholder wrapped in {{}}.

• Remove any unsupported Mustache tags or commands from the template body.
• Replace each unsupported tag with a data tag placeholder in {{}}.
• Use simple variable placeholders such as {{1}} or {{CustomerName}}. Variable keys can be numeric or alphanumeric, and they cannot contain spaces.
• If you send the template with substitutions, pass matching values in ContentVariables. If you create the template with the Content API, define the template variables in the variables object.
