I get an error when I try to install "Frappe Chat" on a new ERPNext instance.
It says "pymysql.err.ProgrammingError: (1146, "Table '_8743f315d5a0b184.tabChat Room' doesn't exist")".
If I uninstall and reinstall the "Frappe Chat" app, the error goes away.

Frappe version :- 15.0.0-dev(version-15-beta)
ERPNext version :- 15.0.0-dev(version-15-beta)
Chat :- 0.0.1(main)

Installation method

manual install
