/definitions/ecosystem_settings.js references launcher.js, which no longer exist

When trying to launch an indexer via
pm2 start --only chain-indexer --update-env
the launch fails with the error message that launcher.js doesn't exist. Changing it to launcher.ts results in a different error when trying to start the indexer:
SyntaxError: Cannot use import statement outside a module.

Also launcher.ts does not seem to be a typescript-converted version of launcher.js, as the original launcher.js has been deleted in this commit 647b6f7 while launcher.ts has just been renamed from indexer.ts

It has happened to me that postinstall script (package.json) fails and I had to run the command manually (after npm install):

npm run tsc && npm run fix-permissions

After that, launcher.js is generated.
