Steps to Reproduce

It was found that the error presents itself when an application contains optimized properties that contain a ‘#’ (Hash/Pound) symbol in the name.


Disabling the merge/batch mode (avoiding the execution of certain type of SQL) resolves the issue.

Disable merge/batch by changing the following prconfig settings:

<env name="classmap/usemergestatement" value ="false" />
<env name="database/batchupdates" value="-1" />

Restart PRPC after submitting the changes.
