PM2 start Fails When Command Contains "yaml" Or "json"

[nossonCotlar]

I am using PM2 to manage a python web service, initiated with a bash command.
this works:

pm2 start 'cd /home/nosson/synchronize && venv/bin/uvicorn server:app --host 0.0.0.0 --reload' --name synchronize
# [PM2] Starting /usr/bin/bash in fork_mode (1 instance)
# [PM2] Done.
# ┌────┬────────────────┬─────────────┬─────────┬─────────┬──────────┬────────┬──────┬───────────┬──────────┬──────────┬──────────┬──────────┐

# └────┴────────────────┴─────────────┴─────────┴─────────┴──────────┴────────┴──────┴───────────┴──────────┴──────────┴──────────┴──────────┘

but when i try to specify a uvicorn log config log_config.yaml, pm2 fails to start the service:

pm2 start 'cd /home/nosson/synchronize && venv/bin/uvicorn server:app --host 0.0.0.0 --reload --log-config log_config.yaml' --name synchronize
# [PM2][ERROR] File cd /home/nosson/synchronize && venv/bin/uvicorn server:app --host 0.0.0.0 --reload --log-config log_config.yaml not found

I suspect this is due to the logic which determines if the supplied command is a pm2 config file:

pm2/lib/Common.js

Lines 283 to 294 in e3a327f

	Common.isConfigFile = function (filename) {
	if (typeof (filename) !== 'string')
	return null;
	for (let extension in Common.knonwConfigFileExtensions) {
	if (filename.indexOf(extension) !== -1) {
	return Common.knonwConfigFileExtensions[extension];
	}
	}
	return null;
	};

which is called when starting the service

pm2/lib/API.js

Line 328 in e3a327f

if (Common.isConfigFile(cmd) || (typeof(cmd) === 'object')) {

Logic for detecting config files as commands should be more precise, possibly checking if the entire command is a valid filename/path rather than a bash (or other) command
