OCS 2.3.6 - error by using Paper Report Plugin

when I try to use the submissions report through the plugin in this link
… / manager / report / PaperReportPlugin
I get a file with the following information (stack trace on):

DB Error: ERROR: operator does not exist: text = integer no caracter 1330 DICA: No operator matches the given name and argument type(s). You might need to add explicit type casts.

Stack Trace:
