Nested exception: "During handling of the above exception, another exception occurred"

I have a project where a PyPortal read from MQTT and display status.

Traceback (most recent call last):
  File "adafruit_minimqtt/adafruit_minimqtt.py", line 1036, in _wait_for_msg
  File "adafruit_minimqtt/adafruit_minimqtt.py", line 1124, in _sock_exact_recv

TimeoutError: Timed out waiting for SPI char

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "code.py", line 247, in <module>

TypeError: function takes 3 positional arguments but 2 were given
]0;🐍1041@adafruit_minimqtt/adafruit_minim TypeError | 9.2.7\
Code done running.

My code seems to not responsible for this error:

while True:
    try:
        mqtt_client.loop(timeout=1)  # Poll the message queue <= Line 247
    except (ValueError, RuntimeError, MQTT.MMQTTException) as e:
        print("Failed to get data, retrying.")
        text_area[0].text = "Failed to get data, retrying."
        mqtt_client.reconnect()  # continue

Initial investigation from Neradoc on discord:

yep the line is wrong, it needs a ("Some message") argument to the MMQTTException

I mean that line, that raises the error:

Adafruit_CircuitPython_MiniMQTT/adafruit_minimqtt/adafruit_minimqtt.py

Line 1041 in 6b0f92f

raise MMQTTException from error

now the real error underneath is the airlift SPI timing out
but that's a different story

What nina firmware are you using?

If it's not current,l (v2.0.0) I would recommend updating it first.

Not sure? This code will print it in the REPL: https://learn.adafruit.com/adafruit-pyportal/internet-connect

Upgrading: https://learn.adafruit.com/upgrading-esp32-firmware/upgrade-all-in-one-esp32-airlift-firmware

Thanks @justmobilize , I was using 1.7.5 and I now run the latest.
It does not change much for me as I previously applied a fix based on @Neradoc analyze for line 1041 of adafruit_minimqtt.py:

               raise MMQTTException("Please insert meaningfull message here.") from error

And that already solved the problem for me.

This is improved now by #249. Feel free to re-open if there turns out to be some better way to handle this in the long term.
