Web API Error

aksharc over 8 years ago

We have created a Web API which will be consumed by the external systems. Briefly, this Web API accepts JSON and starts a process using a!startProcess component.

Now, when I try to access the Web API from Fiddler, I get the success message. But somehow, if the WebAPI is accessed from the external system, it throws following exception with message ERROR com.appiancorp.webapi.WebApiServlet - Error processing request to Web Api Endpoint <Endpoint Name>:
java.nio.charset.MalformedInputException: Input length = 1 and java.nio.charset.CoderResult.throwException. From the latter, I am guessing that it may have something to do with charset. What charset Web API expects? Or is it indeed a charset issue? How could I debug this?

From the error, it seems that you are not sending the expected input format.

Are you seeing any additional detail in the app server log? If not, you might be able to get some more info by increasing the webapi logging levels:

log4j.logger.com.appiancorp.webapi=DEBUG
