Polygon Mumbai Issue

[benjamin852]

I am using the addNativeGas() function on axelarjs. This had been working for me in previous months for my tx going from Polygon to Fantom. But now when I run this hardhat task I get an error saying.

An unexpected error occurred:

Error: could not detect network (event="noNetwork", code=NETWORK_ERROR, version=providers/5.7.2)
  reason: 'could not detect network',
  code: 'NETWORK_ERROR',
  event: 'noNetwork'
}

Not sure if we changed anything for Polygon Mumbai. I tried to run this script the other way around (from Fantom to Polygon) and it worked fine. Here is my execution, it's quite straightforward

   const gasOptions: AddGasOptions = {
      evmWalletDetails: {
        privateKey: connectedWallet.privateKey,
      }
    }


 const { success, transaction } = await sdkGmpRecovery.addNativeGas(
          EvmChain.POLYGON, //Polygon not working
          tx2.hash,
          gasOptions
        )
