Opentrons: bug: Opening door while robot paused crashes robot

[JohnGoertz]

Overview

I have a pause written into my (python) protocols where I need to open the robot door. Sometimes (but not always), this causes the robot to crash. The "run" view in the app resets from "Restart Run" and "Cancel Run" to only "Reset Run", then the robot becomes unresponsive (toggling the Lights button does nothing).

Steps to reproduce

Write python protocol with a protocol.pause (this is action ~1600 in my protocol). Open the door, then close the door. The crash happens at one of those exact moments, usually when opening the door.

Current behavior

Crashing.

Expected behavior

Not crashing.

Hey @JohnGoertz, thanks for the report.

1. Can you confirm your robot is on the latest software version, currently v4.3.1?
2. What's your current "Enable Robot Door Safety Switch" setting?

[JohnGoertz]

Hi @SyntaxColoring, yeah the robot is is on 4.3.1 and the Robot Door Safety Switch is off.

Could you share your full protocol file, as well as any custom labware definitions it uses, so we can try to reproduce and narrow it down?

Preferably as a .zip file posted in this GitHub issue, but if it's confidential, you can also email it to me at [redacted].

We tested this out on our just released version 4.4.0 software, and were unable to reproduce the issue. Given that this release included fixes targeting the pause system, I'm optimistic that we may have fixed the root issue. @JohnGoertz are you able to give try the latest software and confirm whether or not you are still seeing this behavior?

[JohnGoertz]

Yeah, I saw that, hopefully! Unfortunately, it is an intermittent issue, I
can't see a pattern in when it happens and when it doesn't, which I know
doesn't help things from your end. Thanks for trying. I'll update the
software and fingers crossed!
