Which Bubblewrap are you using? I tested against 1.17.1 and it works without issues.

@andreban, I am able to run the one that @maraah1 originally posted, however, I get the same Unexpected token in JSON at position 0 for the following bubblewrap init --manifest https://bitculator.com/manifest.json

I can load https://bitculator.com/manifest.json from the browser, but when running curl -v https://bitculator.com/manifest.json it doesn't return a proper JSON, which is probably what is being served to Bubblewrap. Here's what I get from curl:
