When calling an Appian Web API using an Appian integration object, the response is a HTTP 500 error.
This can happen when the request to the Web API is malformed or contains invalid inputs.
Check to make sure that all parameters being passed are valid, and that the request body is property cast using the a!toJson() function.
This article applies to Appian 17.2 and later.
