Example Code

@app.post('/opr/state/cos/run/gnmi/')
def gnmi_data(input_gnmi: dict):
    subscribe = {
        'subscription': [
            {
                'path': input_gnmi['path'],
                'mode': 'sample',
                'sample_interval': 10000000000
            }
        ],
        'use_aliases': False,
        'mode': 'once',
        'encoding': 'proto'
    }

    with gNMIclient(target=(input_gnmi['ip'], input_gnmi['port']), username=input_gnmi['username'], password=input_gnmi['password'], insecure=True) as gc:
        telemetry_stream = gc.subscribe_once(subscribe=subscribe)

        returnThis = []

        for telemetry_entry in telemetry_stream:
            returnThis.append(telemetry_entry)
            if (str(telemetry_entry) == "{'sync_response': True}"): break

        return returnThis
    
    return ""

Description

Trying to pull gNMI data from a network device. The actually gnmi stuff was tested and works but my issue comes up at the end of the example code. The variable 'telemetry_entry' is just a dict, 'returnThis' is an array of all the 'telemetry_entry's, so an array of dicts...

I found that the error is trigger right after the loop on the line the 'return returnThis'. For some reason, jsonable_encoder thinks this is a Decimal64. The exact input I'm giving it follow this format:
