Unhelpful "can't convert String into Integer"

[abh]

I'm getting an unhelpful "could not run migrations" error that I'm not sure how to fix:

# ./bin/mogbak create --dbhost=mogile.db.foo --dbport=3307 --dbuser=mogbak --dbpass=.... --domain=... --trackerip=10.50.0.20,10.50.0.68,10.50.0.21 /tank/mogile/us-prod-media
error: could not run migrations on /tank/mogile/us-prod-media/db.sqlite

Did it create the db.sqlite file in the us-prod-media directory? Also if you have the mogbak gem installed you should be able to just type mogbak instead of calling it via ./bin/mogbak as it should be in your path.

Try running that with ./bin/mogbak --debug create

Yes, created a 0-byte .sqlite file.

Thanks for the hint about the --debug flag, that helped me get a bit further. Now I am stuck at:

root@linguo:/usr/local/mogbak# ./bin/mogbak --debug create --dbhost=mogile.db.la.sol --dbport=3307 --dbuser=mogbak --dbpass=... --domain=us-prod-media --trackerip=10.50.0.20,10.50.0.68,10.50.0.21 /tank/mogile/us-prod-media
can't convert String into Integer

I tried connecting with the mysql client to the database to make sure the credentials etc are ok, and they are.
