The problem is when running System > Bulk Loader task to modify existing users in batch the Modify User task goes into Audited status and not submitted.
Here is the example of the content of the Feeder file. The last attribute (%STRING_09% attribute) value is set to blank (space character) as we want to keep existing attribute value.

The task details is shown as the following in View Submitted Task screen
IM server log shows following error
2020-10-02 11:42:45,382 ERROR [im.feeder] (pool-32-thread-1) java.lang.ArrayIndexOutOfBoundsException: Array index out of range: 7
Release : 14.x
Component : IdentityMinder(Identity Manager)
In the Screen configuration of Profile tab of the Modify User task, the %STRING_09% attribute has been defined as checkbox, with Checked Value (value when the checkbox is selected) is set to 1 and Unchecked Value is set to 0.
This issue won't happen if %STRING_09% is defined as Text Style or positioned not as the last column.
To workaround this problem, you can add additional comma (",") at the end of the line after the last space character in the feeder file.
