Exception occurs on reading pxMatchScore when UDFs are disabled



UDF's are disabled and an activity is configured to check for duplicates using 'SeekCases'. This activity internally evaluates the CaseMatch rule to calculate the match score and runs a report definition which populates the duplicates. An exception occurs while running the report definition.

Error Messages

There was a problem getting a list : code:0 SQLState:42883 Message: ERROR: Function Pegadata.pr_read_from_stream(unknown,character varying, bytea) does not exist Hint:No function matches the given name and argument types. you might need to add explicit type casts position :320

Steps to Reproduce

  1. Disable UDFs
  2. Run the SeekCases activity with the case match rule as the parameter. Error occurs during runtime. 

Root Cause

While running the CaseMatch rule, pxMatchScore property is used internally while fetching data in a report definition. In that report definition, pxMatchScore property is read from the BLOB column using pr_read_from_stream because UDFs are removed. This caused the error in the CaseMatch rule execution.
