Missing argument "db_tablenames" with APScheduler

[wpmjones]

I can create a job successfully and it appears in my postgresql database. But when I try and modify it, I get the following error:

HTTPServerRequest(protocol='http', host='192.168.1.120:5678', method='PUT', uri='/api/v1/jobs/65a6eabfe79d4e46b44762cf5c5b6804', version='HTTP/1.1', remote_ip='192.168.1.119')
