[BUG] Perspective.SessionProps Error in Designer

Dear all,
I am currently running the b2019021702 build.
The following error occurs when I save in the designer:

12:33:01.536 [AWT-EventQueue-0] WARN Perspective.SessionProps - Unable to obtain session props for save.
java.lang.IllegalArgumentException: Resource cannot be overridden.

Thank you.

You might be hitting this: Overridable Resources Bug

Dear Kevin,
when the bug will be fixed inside the nightly build?
Thank you.

Did you try running the Python script in the post I linked to?

Read the linked post - the bug has already been fixed for anyone going forward. If you don't have a backup you can restore that's older than either of those two affected versions, you can try running the script @Kevin.Herron posted in the linked thread to 'fix' your resources.

Ok, thanks. The “overridable” properties are fixed.
