I updated from 22.214.171.1244 to 126.96.36.1991 lately and now have this runtime exception while executing a custom procedure used to automate Apex importations that is used weekly for more than a year:
What's triggering this is a call to apex_application_install.install(). Whatsoever the procedure seems to execute just fine and so is running the imported Apex application: A re-export of the above-mentioned imported application script reveal no difference with the initial script.
I re-tested with older versions of Toad and were not able to replicate the issue. The same process has been done by another colleague on a different machine/session/user as well.
Apex version of used db is : 20.1.0.00.13
Oracle version is: 19c Enterprise Edition.
Not sure if you can troubleshoot with not so much meat on the bone, so let me know if more is needed.
