Might this error be due to the problems we are having with the OSV data source?

[terriko]

I've merged #4929 which should solve the OSV problem so I'm going to try updating this branch

[joydeep049]

I think this can be merged now @terriko @anthonyharrison

After this is merged we have a full no-scan mode with proper outputs. Request anyone who has time to test it.
