When running Data Profiler in Datamaker on a any one or more registered tables it gives the message "NULL Object Reference at line 148 in open event of object w_data_sample." as in the below screenshot and crashes out.
Release : 4.10
Component : Datamaker
Using a connection profile which the user is not the owner caused the issue.
Engineering fixed the issue in the new version of Datamaker GTDataMaker-4.10.9.0.zip and now users can use a connection profile which they are not the owners and able to run the data profiling without any issue.
If anyone using the prior version GTDataMaker-4.10.9.0.zip, they can create a new connection profile or use the one which he/she is the owner as a workaround to resolve the issue.
The connection profiles information is available in GTREP table GTREP-PROFILE.
