Unable to reports. System displays an error message: undefined method `multi_select?' for nil:NilClass

I have migrated these reports from the old CPIMS v1.6 to the v2 version. I have followed the official documentation on the Primero GitHub repository to complete the migration.

I can see all the reports that are migrated, but when I open a report I am getting the error message.

@srinivasa.puneeth This is mainly due to difference in type of fields used in reports. May I know what was the reports and what are the columns and rows used along with any filters used.
