According to the userguide of activiti-rest, when an error occurs, and the headers "Accept" (and Content-Type) are set to application/json, this content appears:
{
"statusCode" : 404,
"errorMessage" : "Could not find a task with id '444'."
}
But in version 5.17 this has changed into:
{
message: "Not found",
exception: "Could not find a task with id '444'."
}
When an Exception occurs, a stacktrace is returned instead of this json object. For an example see the attached file
and look for userTask "sid-03ECA751-1348-4729-969E-65A6B4EB66B5". In the scriptTask this happens:
if (var1 != 'ok'){throw new Exception ('<error>correct value for var1 is: ok</error>')}
In the past this body was returned:
{
"statusCode" : 500,
"errorMessage" : "<error>correct value for var1 is: ok</error>"
}
Now I got this (headers included):
