Undefined protocol error #165
Description
Hello! After updating :mox from 1.1.0 to 1.2.0, we started encountering the following (blinking) errors in our CI tests. Downgrading back to 1.1.0 resolved the issue. Could you please take a look?
1) test /addresses/{address_hash}/nft/collections test filters (BlockScoutWeb.API.V2.AddressControllerTest)
