Thanks for submitting a repo to see the problem.

Well, it simply happens because the collect-fbts script is using the contents of i18n/fbt/.src_manifest.json (in your repo) to collect fbt strings but there simply isn't any.
That file is empty because your current repo does not contain any fbt() or callsite in the src folder.

If you add this code in App.tsx for example:

import fbt from 'fbt';
fbt('foo', 'bar');
const f = <fbt desc="test">foo</fbt>;

And then run yarn manifest && yarn collect-fbts, you should see a different result:
Actually, it's this other error...

Error: /.../dooboo-expo/src/App.tsx: Invalid option "__self". Only allowed: project, author, preserveWhitespace, subject, common, doNotExtract

Then you should follow the advice in that comment to workaround it: #137

And also add the --options __self to the collect-fbts yarn script.

Here's a patch to summarize the necessary changes: https://gist.github.com/kayhadrin/0429148128d1042f808666301c423c99
