Problem with Zoom Proctoring #8

Closed trungnn94 closed 2 years ago

trungnn94 commented 2 years ago

Hi,

I am using SEB Server 1.2-stable [production/bundled/dockerhub]

Steps to reproduce the behavior:

  1. Go to 'SEB Server'
  2. Click on 'Monitoring' -> 'Running Exam' -> 'Monitoring'
  3. Click on Session with status Active -> 'Single Room Proctoring'
  4. See error HTTP 401

Screenshots My proctoring settings image

when i click to 'Single Room Proctoring'... what I did wrong with my proctoring configuration? image

I'm pretty sure my zoom account is okay (licensed and used daily)

Trung Nguyen,

Hi

It seems that your Zoom account is not properly setup and the Server URL seems to be wrong. This should be the base URL of your on premise Zoom account, something like "https://[your-institution-name].zoom.us/" or you can also try the base Zoom URL "https://zoom.us/".

When a SEB client is connected you should also see it in the collecting Proctoring Rooms on the main monitoring view: image

If this is not happening, something is wrong with the proctoring setup. You can also check the SEB Server logs of your setup the get more information on this. Since the Zoom proctoring integration is still in an experimental state, error handling needs to be improved.

Hi,

I'm trying to change the URL but it doesn't seem to work. The collecting Proctoring Rooms on the main monitoring view is not showing. Below is my seb-server log, hope this helps.

Trung Nguyen,

Hi and thank you for the logs

It seems that your Zoom API is responding with unexpected data while SEB Server tries to create a new meeting room -->

Caused by: com.fasterxml.jackson.core.JsonParseException: Unexpected character ('<' (code 60)): expected a valid value (JSON String, Number, Array, Object or token 'null', 'true' or 'false')

The '<' character indicates that the Zoom API responds with a wrong format (should be JSON) either HTML or XML. Unfortunately I'm not able to see more at this Point because the logging is not printing the whole Zoom response in this case. What SEB Server is doing is the following: For every new Zoom Meeting a Zoom User is created to manage the Meeting. This is to avoid request limits for the meeting that are restricted per Zoom User. Then create a new Meeting with this User. The creation of the meeting seems to fail on your account.

My first assumption is that your account has not the needed rights and/or privileges to do so. But the cause may be another since we are not Zoom API experts.

SEB Server uses the following Zoom API requests to create new Users and Meetings:

https://marketplace.zoom.us/docs/api-reference/zoom-api/users/usercreate https://marketplace.zoom.us/docs/api-reference/zoom-api/meetings/meetingcreate

If you have a curl Tool like Postman you are able to use this API endpoints with your Zoom Account and are able to figure out what exactly happen and what Zoom is responding.
