Cannot export local transaction to tenderly using cli

[peculiarity]

Tenderly Current CLI version: v1.4.7 Hardhat Version: 2.12.2 Compiler version: 0.8.15

Trying to export a local transaction. It used to work bu not anymore.

The export fails with the following error message: Couldn't read Hardhat config file: When I debug it there is this error:

[eval]:20
                var jsonConfig = JSON.stringify(config, (key, value) => {
                                      ^

TypeError: Do not know how to serialize a BigInt

Let me know if you need anything else

Edit: With 2.8.0 hardhat it works just fine not sure where the problem is
