Create CHEQD DID (did:cheqd) feature not working

[ChangoBuitrago]

When you try to create a Cheqd DID from the Wallet (e.g. the hosted wallet https://wallet.walt.id/) you get the following error:

{exception: "true", status: "Bad Request", code: "400",…}
code
: 
"400"
exception
: 
"true"
message
: 
"Failed to finalize the did onboarding process.\nCheqd registrar returning \"The operation failed due to an internal error. Please try again: Error: Invalid base64 string format\""
status
: 
"Bad Request"

=> Invalid base64 string format

Thank you.
