I created the signatures tool a few hours ago, around 2020-03-13 19:30 UTC. When I tried to test a portion of the tool that depends on a database query, it errored with pymysql.err.OperationalError: (1045, "Access denied for user 'tools.signatures'@'10.64.37.15' (using password: NO)"). I looked in /data/project/signatures, and found that there was no replica.my.cnf file. Something probably went wrong in the user creation scripts.
