Can't broadcast transactions with Asigna

[jfstn]

Describe the bug Using the last @stacks/connect update, 8.1.8 that fixes Asigna connection by fixing the request call for that provider I'm unable to broadcast transactions.

To Reproduce

1. Go to Asigna Multisig;
2. Go to Apps;
3. Select Zest Protocol;
4. On the top right click on Connect Wallet;
5. Select Asigna provider;
6. Fund Asigna's wallet;
7. Attempt to supply STX;
8. Error is thrown while serializing values;

Expected behavior Asigna should pop up and allow the user to confirm the transaction;
