fetchAccount() throws "TypeError: Cannot destructure property 'publicKey' of 'account' as it is null." error on accounts not included into ledger

[dfstio]

Calling fetchAccount() for the account not included in the ledger with o1js 0.18.0 and one of the following devnet endpoints:

https://proxy.devnet.minaexplorer.com/graphql
https://api.minascan.io/node/devnet/v1/graphql

throws the following error:

TypeError: Cannot destructure property 'publicKey' of 'account' as it is null.

To whoever from us is fixing this: It means that the node returns something which we don't recognize as an error / missing account, and try to parse as an account.

Seems the graphql endpoint behaviour has changed
