When an external system invokes an Appian Web API with a request body that is not UTF-8 encoded, the call to the Web API may fail with the following error in the application server log:
ERROR com.appiancorp.webapi.WebApiServlet - Error processing request to Web Api Endpoint importpropertyINFO [stdout] (ajp-/0.0.0.0:8009-29) java.nio.charset.MalformedInputException: Input length = 1
The request body is not UTF-8 encoded.
Ensure that the request body for any calls to Web APIs are UTF-8 encoded.
This article applies to all versions of Appian.
