I am trying to add some filters to the data retrieved from an entity query and keep encountering an error

"An error occurred while retrieving the data. Details: The data source [jdbc/Appian] cannot be reached or its configuration is invalid. Details: could not extract ResultSet"

I keep encountering this error while trying to add some filters to the data retrieved from a query entity. The query runs fine and retrieves all the data, however, when I go to add some dynamic filters to this data I keep encountering this error. I am reaching out to see if anyone from the community has come across the same error and what solution worked for them. Basically trying to add a few specific data filters to a search bar in the application. Any suggestions are welcome. Thank you
