@doublemis1 what does Apply needed changes to provided script step mean?

[doublemis1]

in zip file there is a script with the reproduction and need update the discriminator, path to paa discriminator and passcode.
However the issue was visible before:
#33989

Now I am looking at this PR, which handle other issue found on our side:
#34231

I think that we can close this specific issue.
