Cause:
If only a select number of reports appear to error out, the cause of the error is from the parameter type of the report parameters. Most likely the parameter type is set to ‘check list’.
Resolution:
Change the parameter type to any other ones like ‘lookup edit’.
Afterward, save and reload the report onto the Portal and test to make sure it runs.
