Apparently you're trying to cast some empty-string value(s) of l.assetid
to bigint.  Even if the test for that weren't commented out :-(, you
can't really assume that it will be applied before the cast is done.
You could possibly make this work without errors by doing

left join on CASE WHEN l.assetid != '' THEN l.assetid::BIGINT = e.entityid ELSE false END

but don't be surprised if the performance is horrid.

On the whole I'd strongly suggest rethinking your data representation;
the reason this is giving you trouble is you made a bad choice of how
to represent l.assetid.  Perhaps it'd work better if it were a bigint
column in the first place.  It's not clear exactly what you intend the
empty-string entries to mean, but if they mean "unknown" then it'd be
better to use NULL for them.
