Pega 8.2 Upgrade error

Hi All,

We were trying to upgrade pega from 8.1 to 8.2. While running the upgrade script, we are getting the below error and the installer is stopping. We have updated the value of bypass.pega.schema property in the file and retried the upgradation but its throwing the same error.

Are you performing in-place upgrade? Please attach the entire upgrade log. The referenced table is new to pega82 I wonder if the DDLs have been correctly applied - check the database if that table is created or not.

Quite odd here: you are upgrading to 8.2.3? but the codeset version points to 8.1.3 (codeset version should be 08-02-04) from the log. Is it possible you are using the wrong distribution image version?

While verifying the sql files generated by the upgrade scripts, we found like some queries are missing. I am attaching the sql files generated.

Could you try running the generateddl script (with --action upgrade) and see if this generated the expected SQL?

This was issue with the generated scripts. Now the issue is resolved and I was able to complete the upgradation process. But after the server restart, I am getting below error in the browser wwhen I tried to launch pega.
