When running the demo, it is always returned:

Error while adding chain: Error: Data error

This seems to be coming from the tiny-inflate and specifically from here that returns an error due to invalid length

This should only happen if you had cloned the repo before #2506 and didn't run prepare.mjs since then

Managed to reproduce. Have no idea what the problem is. Decoding the base64 and re-inflating the buffer within prepare.mjs using zlib works fine.

I'll restore pako after #2522
