Hi,
I have implemented with the Flowable Modeler a process that obtains data from a form and sends it through an HTTP request to an Apache Tomcat server. However, if I don’t field all the fields (and I leave empty any of the ones that are not required), it is detected as malformation and throws the next error:
<!doctype html>HTTP Status 500 – Internal Server Errorh1 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:22px;} h2 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:16px;} h3 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:14px;} body {font-family:Tahoma,Arial,sans-serif;color:black;background-color:white;} b {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;} p {font-family:Tahoma,Arial,sans-serif;background:white;color:black;font-size:12px;} a a.name .line {height:1px;background-color:#525D76;border:none;}

Note The full stack trace of the root cause is available in the server logs.
Apache Tomcat/9.0.27
Does anyone know how to solve this issue? Thanks in advance.
