The (partial) deployment left the administrative application (aka backend) in some inconsistent state. The fields request.type and request.guid were removed, because of the introduction of the table subscription. Subscriptions are supposed to have a link to the address table, which is not present yet. The changes are reflected in the export, the export currently exits with a fatal error.
I imported the DB dump of the live database into test, ran vendor/bin/doctrine orm:schema-tool:update --dump-sql and executed the SQL statements that were generated. unfortunately the address table was already generated for the test db, so i missed that. I've created it, the export should work now.
OK, looks good. I just ran the export script with the actual user.
Strange, that the error output is not printed when using our own users, though. I suspected some per-user setting, but couldn't find any. Do you have any explanation for this?
