Missing code or state parameter

[barbergeek]

So I am having the same issue as was previously reported. "Missing code or state parameter" when I try to install the application from the App Marketplace. Yes, I have carefully reviewed that thread but did not see an actual resolution to the issue, or anything that helped me to fix the problem. I have crosschecked the client id, secret, and verification token as well as the URL for the callback and whitelisting. My server is available externally @ https://[servername].duckdns.org. I am also using the NGINX Home Assistant SSL proxy along with the Duck DNS add-on. Any further guidance? Does someone have an example of a known good installation URL?

I'll also add that I'm running core 2021.12.10 on Home Assistant OS 7.2 with supervisor 2022.01.0

Version of the custom_component

0.82

Configuration

zoom:
  - client_id: [clientid]
    client_secret: [secret]
    verification_token: [token]
    name: google

Describe the bug

HA Server reports:
Missing code or state parameter in http://[my valid server name]/auth/external/callback?code=[randomcode]

I also note that it reports http: rather than https:

So i fug up this ticket which had a similar issue but was resolved, not entirely clear how.... But based on the steps suggested in #22 I did try the following:

I checked my external URL in the config was correct
tried my nabucasa one with remote on.

Added the correct URL in the event subscription and in the callback hook and this time I got the same error but oddly it was https this time in the URL it displayed 🤷

are you attempting to install the application from the Zoom website? If so, that will not work and will lead to this error. You instead have to add your client ID and Secret to HA and then set up the integration. As part of the integration setup, you will be sent to the zoom site to authorize and install the application in your account

[barbergeek]

Ah. Bad assumption on my part.

I may have made progress, but am getting a different error now when trying to start the integration. I changed the name in my configuration.yaml file to match the App Name I used in the App Marketplace. It now fails with this error:
Logger: custom_components.zoom.common
Source: helpers/update_coordinator.py:219
Integration: Zoom (documentation, issues)
First occurred: 11:47:44 PM (1 occurrences)
Last logged: 11:47:44 PM

Error fetching zoom data:

... continuing to diagnose and I'll check the closed issues list to see if there is anything relevant.

[barbergeek]

So I uninstalled and reinstalled the component and removed the "name:" from the config. It asked me for an account name when I reinstalled it and the log reports "Successfully authenticated". The next line is the "Error fetching zoom data:" mentioned in the previous comment.

I will note that I don't see this happening in the instructions: Authorize the app for the Scopes that were configured earlier.

[barbergeek]

My apologies. Pop-up blocker was preventing the zoom page to open, and I never noticed. I uninstalled and re-installed and it went much better. If I have other issues, I will open a new issue.

CHECK YOUR POPUP BLOCKER!
/facepalm

[raman325]

it happens! thanks for reporting back. @johntdyer were you able to resolve your issue? see my response above for my suspicion about the mistake you are making

[johntdyer]

@raman325 i am still getting an error... It appears to successfully recognize the plugins config but the entities are not available

are you in a company account or in a personal account? If you are in a company account, it's possible that your company is blocking the polling API. The intent of the logic that is throwing the log statement was to catch when the internet goes down, but that may be too aggressively making the sensor unavailable. But that would only be the case if you are monitoring a company account

[johntdyer]

@raman325 it is a corporate account. Do you have any documentation on where this limit is configured? I am pretty sure I can ask them to change it if i know were to tell them to look

[raman325]

you would need access to event subscriptions for user activity as well as the chat_contact:read scope

[raman325]

actually, looking at your error again, it seems that Zoom considers our request a bad request which indicates a problem on the client side. Can you try removing the zoom integration and setting it up again for the same account? Be sure to do all the setup within HA (except for the part where it opens up the zoom site for you to authenticate)

[johntdyer]

@raman325 so I have tried that several times with no luck

[raman325]

got it well I doubt it is the permissions on the corporate side but maybe it's worth asking based on this comment #52 (comment) ?

[johntdyer]

I am not seeing chat_contac:read

I have the following scopes

[johntdyer]

nevermind, i found the scope... I also noticed that I wasnt putting out account name int he first field.. It was prefilled w/ "Zoom" and I just assumed it was supposed to be that

[raman325]

OK so is the issue resolved now, or are you still seeing the sensors as unavailable?

[mhrynkewycz]

Hi everyone, I am still getting the same error myself. Missing code or state parameter in https://xxxxxxx.duckdns.org/auth/external/callback?code=gOoR3T1rmG__MfcsQaMTGeu6UxM2IWxxx

Did anyone get to the bottom of this?

[rmiles7721]

Getting the same missing code or state parameter as well.

[raman325]

did you go through the config flow or did you try to install the app from the Zoom site?

[mhrynkewycz]

I’ve tried both options. Either way I get the same result.

so you installed the zoom integration in Home Assistant, clicked the button in HA that opens the Zoom log in screen, logged in, and then the next thing you see is Missing code or state parameter? That typically only happens because the initial setup with Zoom didn't include this information from HA, but HA should add that to the URL when it takes you to the zoom login automatically

[Normanras]

Not sure if this is helpful, but I originally tried via the browser (dumb!) and got the error, which brought me to this issue. Despite that, I went into HA and checked everything, and the sensor works and is pulling information. The sensor changes to connected and disconnected appropriately.

I think the creation of the app through the browser does work, the caveat is to not click "Add" on the last screen. Just ignore that, go into HA and verify that it works. I hope that helps!

I know this is bit of an aside, but @raman325, do you know about any limits to the connection? If I quickly restart a meeting (within 10 seconds) of stopping a meeting, my sensor doesn't change from disconnected to connected again. If I wait a bit, then it picks up the change in status. Not sure if Zoom thinks the quick changes are some sort of spam bot.
