Mech client hangs with ConfirmationType.OFF_CHAIN

[evangriffiths]

The interact method does not return with confirmation_type == ConfirmationType.OFF_CHAIN

In stdout I see

Created on-chain request with ID 56439741347897565096390923836077361339766652372962787639228859560995999907820
Waiting for Mech response...

but in the mech web UI here I can see that the request matching that ID has a corresponding response (i.e. an. IPFS link)

To reproduce:

from mech_client.interact import ConfirmationType, interact

private_key_path = "..."

def _interact(confirmation_type: ConfirmationType):
    interact(
        prompt="Is the sky blue?",
        # Taken from https://github.com/valory-xyz/mech?tab=readme-ov-file#examples-of-deployed-mechs
        agent_id=6,
        private_key_path=private_key_path,
        tool="prediction-offline",
        confirmation_type=confirmation_type,
    )


_interact(ConfirmationType.WAIT_FOR_BOTH)  # works fine
_interact(ConfirmationType.OFF_CHAIN)  # hangs

@0xArdi i think the node uri-acn.staging.autonolas.tech:9005 is not sending the response here response = await connection.receive()
