Get Voucher not working on WebGL

[juans-chainsafe]

Describe the bug
Get721Voucher and Get1155Voucher are not working correctly on a WebGL build, I get a CORS error on https://lazy-minting-voucher-signer.herokuapp.com/voucher721?receiver=0xabed4239e4855e120fda34adbeabdd2911626ba1 endpoint

To Reproduce
Steps to reproduce the behavior:

1. Add the VoucherMinter721 or VoucherMinter1155 prefab on SampleScene
2. Build and run with WebGL
3. After build finishes, do the login connecting to a wallet on the browser
4. Click on Get Voucher Mint 721 (or 1155)
5. See console error

Expected behavior
Voucher is generated and the user needs to sign the transaction on his wallet

This needs to be fixed in the heroku app, nothing to do on the SDK side. Do we know who owns that?

yes, @sneakzttv

@FSM1 has ownership of this at the moment, the card needs to be refreshed, however i was booting up a local instance with this on docker and it doesn't seem to be happy. I don't think our api endpoint is STORAGE_API_URL="https://api.chainsafe.io/api/v1" anymore as it doesn't seem to be active on simple inspection. Secondly whilst a 3rd party like https://www.back4app.com/ is free for now, there's a good chance they'll charge in the future and we'll be in the same situation. I'd suggest just expensing heroku and adding dyno hours so it doesn't sleep as the config is already there. That or we move to ecdsa verification solidity side and teach users how to create vouchers using that as it's free forever.

https://api.chainsafe.io/api/v1

For what I see, https://api.chainsafe.io/api/v1/ is working but is using a Bearer authentication

This is what i get when i hit that api with insomnia and a bearer token with a local docker instance running

[sneakzttv]

if we just renew that card on heroku and expense the $5 a month for the dyno hours so it doesn't sleep this issue is resolved xD
