REST node not supporting all characters

Hi,

I’ve created a process that generates an API Post with XML as body by using REST extension, but is only working if not adding many lines. The system is giving me either 400 or 500 message codes when I include many lines.

Does anyone knows if there is any additional setup required to enable POST API webservice to manage all characters we need to use.

I would expect the server error message to contain some information about the actual error. 500 is an internal server error, i.e. a problem in the server. 400 is a generic client error. Without further information it’s hard to tell what the problem is and how to solve it. One reason could be that the web service you are calling isn’t capable of handling chunked requests which is what the REST nodes do when the body gets larger.
