70155: Request Is Missing Required HTTP Headers

The JWT received by Twilio along with the request has defined a set of HTTP headers that must be validated. The actual request is missing at least one of those headers. This is a Public Key Client Validation Error.

• Make sure you are using the latest Twilio helper library.
• Make sure the JWT does not declare unnecessary headers.
• For the details on JWTs used as part of Public Key Client Validation, see the documentation
