These are the errors I got with my docker-compose.yml and dockerfiles

[2022-04-10 02:44:49] ERROR: failed to launch: determine start command: process type web was not found
[2022-04-10 02:44:49] ERROR: failed to launch: determine start command: process type web was not found

I’m not sure what the problem is or even what a solution is.
