[WalletConnect v2] Can't create a Safe when optional namespaces are present

[megakoko]

Bug description

We're using Gnosis Safe via Wallet Connect 2 and we're getting different errors after establishing the session with optional namespaces.

The session IS indeed established just fine after connecting the wallet. We're getting the errors below when trying to create the safe. We're not receiving any events from Gnosis, no transactions to sign. These errors pop up in the top right corner of the web page.

If we don't pass any optional namespaces then it's working just fine, we get the request to sign the transaction and the flow goes on.

Other DApps do work when optional namespaces are present in session connection request.

Below are some of the errors we get:
