ERROR - WebServices: com.mendix.core.CoreRuntimeException: Failed to commit
0
Hi, we made some of our incoming webservice messages persistable, as we want to first put them into a queue and process them lateron. Every once in a while (a few days up to a week) we get this error: ERROR - WebServices: com.mendix.core.CoreRuntimeException: Failed to commit. This happens before the WS_ Microflow (as defined in the Operations in the webservice) is called in which we put the message into the queue. What can cause the WebService to generate this error? Funny thing: after restarting the app the same incoming message is processed successfully... The stack trace: 2020-03-22 20:01:57.771 ERROR - WebServices: Exception occurred while processing webservice request 2020-03-22 20:01:57.771 ERROR - WebServices: com.mendix.core.CoreRuntimeException:
