Ticket: User Preferences - http PUT 401

MongoDB University M220P: MongoDB for Python Developers

When I was trying to save the preference - getting 401 error from the debugger:

Also see the debug output attached from browser, complains on missing header.

401 means unauthorized. Check your user’s authorization, it should have read/write access.

Kanika,
thanks for the response. My take below:

I was able to create a sign-up record which means I have both RW access at filesystem and in the database. I did verify few times the permissions and made it open for everybody on the folders.

Just to reconfirm I signed-up again with a new name, email and it has created it successfully. I am pasting the output from run.py during signup and status update and you will see POST during sing-up passed but PUT for user-pref and for logout also failed(which i just realized).

Sending you message to share the code.

I am having the same issue, code looks fine, but am getting the “401” http error, same as Suresh. Please help.

Also, when I run the “Preferences” test, I get this error, which doesn’t seem to have anything to do with the code I am changing:

Not sure if this is a separate issue - when i run the test via the web interface, I get the error: “User Preferences: preferences weren’t saved correctly”. All other tests so far I have done through the website and have worked fine.

#7

From your prompt it looks like your virtual env is not activated.

#8

steevej-1495 - Do you mean the “conda mflix” VE? It was active.

#9

Yes

Usually, anaconda modifies the prompt to indicate the active virtual environment, such as

(mflix) C:\Temp\...>

Your prompt does not show that. May be yours is different. Sorry.

#10

That’s because I had started the VE in another window. Don’t know why… :slight_smile:
I started in the same window, still get the same error:

And what about the 401 HTTP error I get in the application? Are these two issues linked? I’m stuck at this point in the course till this is resolved.

#11

Have you install the requirements in the same terminal as the one where the VE is installed?

#12

Yes. All the other labs have worked fine.

#13

Hi. So does anyone have any ideas on the HTTP 401 error I am getting? That is the main issue here, and I would really like to finish this course.

kanikasingla - you helped another person before with this - can you share what was done?

Thanks.

#14

I also noticed that when I click the “Logout” link on the website, I also see the HTTP 401 error and the record in the sessions collection is not deleted.
Creating a user works fine, logging in and creating the session record also works, but when calling the “logout” or “update-preferences” methods it fail:

Seems like a permission issue, I checked the “m220student” user account on the cluster, is an admin so should not have any database privilege issues:

I’m really stuck, any help would be very appreciated.

#15

Does pytest -m user_management works without errors?

Http put 401 error
#16

Hi @steevej-1495 - actually none of the command line tests work - get the same
TypeError: attrib() got an unexpected keyword argument ‘convert’
error as above - but the web based tests work fine.

This may be a separate issue, and I am not that worried about it, as I can successfully test and get a return code, so I have a work around. My main issue is the HTTP 401 error when accessing the two methods I mentioned above.

#17

So I skipped this Lab (not sure why they call it a “Ticket” in the course!) and progressed on with the course. Am in the “Create/Update Comments” section, and am getting the same HTTP 401 error when it calls the “comment” api.

As you can see, the POST calls return an error - except for the “user” API when I created a new user - that works fine. But why are the other POST calls failing?

PLEASE HELP!!

#18

UPDATE: to rule out user permission issues in the database, I tried using Jupyter to perform an insert into the “comments” collection - which was successful:

This uses the exact same credentials to connect to Atlas as the MFlix app does.

So… what could be throwing a HTTP 401 permissions error?

#19

@Darwin_LeMay

I did some changes and now all my test has been passing and as well as User_Preferences Ticket also has passed. 401 error still there and preference is not added to the user collection however everything is green…phew & good-luck!

#1 .ini - quoted the superkey
#2 {"$set": {“preferences”:prefs}}

#20

Can you confirm that the user “m220student” in your Atlas database or your local database does have read/write all databases as their permissions?

It is unusual to see a 401 HTTP return code unless there is an aspect of the user permissions incorrectly set.

Thanks!
