Hi,

When i invoke a contract function AMOY\_POLYGON\_TEST chain in Sandbox, I am getting Fireblocks Internal Error, does Sandbox environment supports contract call to AMOY\_POLYGON\_TEST chain? I don’t see any node status AMOY\_POLYGON\_TEST in [https://sandbox.status.fireblocks.com/](https://sandbox.status.fireblocks.com/)

The transaction ID is : 21c7fe78-4fa9-4b2e-8802-34c85660a91d

Hi @junmeng-t the Sandbox environment does support Contract Calls for `AMOY_POLYGON_TEST`

Looking at the logs I found the following error

`ESTIMATE_GAS_LIMIT: Request failed with status code 418, with reason: 'NoneType' object has no attribute 'eth'`
