Photon crashes during execution of UDF

During the execution of a UDF, the Photon client can crash. Possible errors include:

Error in changeCurrentEdit Error: Transformation engine has crashed. Please reload your browser (exit code: null; message ID: 161)

Solution:

This crash can be caused by a number of issues. You can try the following:

1. D s config

2. Bump the value for udf-service.udfCommunicationTimeout setting. Raise this value a bit at a time to see if that allows the UDF to execute.
