Control panel crashes after chat bot is added #45

Closed hecksadecimal closed 5 years ago

hecksadecimal commented 5 years ago

Adding a chatbot and a channel associated with it, then restarting the control panel causes it to crash when it connects to the tgstation-server backend. Deleting the chatbot entry from the database and then restarting the backend remedies the issue in 4.0.1.3 and allows the control panel to connect again without crashing.

Edit: After more testing on the latest release, removing the entry in the database no longer solves the issue.

Backend is running on a ubuntu linux server 18.04 installation with a MariaDB sql server. Control panel is running on a Windows 10 Pro machine.

This is actually an issue with the control panel, not the backend
