I'm by no means qualified to professionally answer this topic, but I would recommend that you actually know the chords in the chord progression. That way your bass solo will be based on each chord scale as the progression moves.
Let's say the Dminor progression was: D minor7th, A minor7th and C7 (dominant).
Then would want to base your phrasings on the notes in the chord scale>>> DFAC, ACEG, CEGA#
But as the the former replies suggest, you should play what you're feeling and see if it fits the mood of the song. Noone likes a forced bass solo after all ...
