Description

Account creation fails for both EOS and TLOS chains.
UI report "Error This Account Name has already been taken." even though the name is not taken.

The dev console of Anchor shows a 400 error on the POST request of name "account_query_exception" to:
https://eos.greymass.com/v1/chain/get_account for EOS
https://telos.greymass.com/v1/chain/get_account for Telos

Platform

Desktop (Linux)

Steps To Reproduce

On Linux 24.04 LTS using Anchor 1.3.12 .AppImage

1. Download AppImage
2. Import an account (may be optional)
3. Go to Tools => Create Account
4. Fill out the form (with an account name that is not taken)
5. Encounter the bug without being able to continue account creation

Anything else?

The Wombat wallet chrome extension is also encountering issues with account creation on EOS but is working on TLOS.

The EOS authority website also seems to be encountering an issue with account creation that may be linked to this bug:
"An error occurred. It could be related to the input or the account creation service is down. Please try again"

This is a duplicate of #1378 but on a different OS and this one has more details to locate the bug so I won't delete it myself

I believe this is the result of a breaking change in the Antelope/EOSIO APIs, which is likely why so many services/apps are impacted. Some services may still be operational (like it working on TLOS) because they are running older API versions.

The quickest way I think we'll be able to create some sort of solution is migrating this functionality over to Unicove.com. This would allow any Anchor user (or users of any wallet) to login and perform the required actions to create an account.

I've created an issue on Unicove to track this: greymass/unicove#338
