'_xsrf' argument missing from POST

[LintangWisesa]

I've followed all the setup instructions: install jupyterlab_email package, jupyterlab_email JupyterLab extension & configure jupyter_notebook_config.py. When JupyterLab activated, first it will ask for the email password. Under JupyterLab File menu there is an option to Send Emails. But when I want to send an email, there is a popup message:

Something went wrong!
Check the Jupyter logs for the exception.

On Jupyter logs I have these following lines:

[W 14:38:30.180 LabApp] 403 POST /email/run (::1): '_xsrf' argument missing from POST
[W 14:38:30.182 LabApp] 403 POST /email/run (::1) 3.00ms referer=http://localhost:8888/lab

What's wrong with this? Is there any solution for this? Thanks in advance.

Can try disabling xsrf check in your jupyter config and see if that works?

Can try disabling xsrf check in your jupyter config and see if that works?

I've just tried to disable xsrf check by adding this line:

c.NotebookApp.disable_check_xsrf = True

on jupyter_notebook_config.py, then re-installing & re-setting jupyterlab-email. Still do the same & got this on jupyter logs:

Its HTTP status code = 500, internal server error?

[Zj-Lan]

I got the same error. Any solution?

[timkpaine]

@Lanzzzzz did you disable xsrf and get the same 500?

[Zj-Lan]

@Lanzzzzz did you disable xsrf and get the same 500?

Yes, I did, and I also got a warning email from Google saying a login attempt from a non-google app has been blocked. Could that be the reason for the error 500?

[timkpaine]

Yep you need to allow less secure apps in google.

[Zj-Lan]

I allowed less secure apps in google. Still doesn't work. My error logs:

Exception: Error during conversion! indicates it was unable to nbconvert the notebook. Does nbconverting the notebook to html work for you normally?

I tried nbconvert directly. It works fine.

And I also added some printout in _email.py to try to find the problem.

I found the path looks abnormal with a /. output:

111111111111111111111111111111111111111111111111111111111111111111

I also added a printout in your nbconvert.py ,

output:

22222222222222222222
['D:\\Python\\Anaconda3\\python.exe', '-m', 'nbconvert', '--to', 'html', '--temp

hide_code_cells_html_email.tpl', 'C:\\Users\\Lanz\\AppData\\Local\\Temp\\tmp9h74
2wku\\mammal_sound_test', '--output', 'mammal_sound_test.html']

I found that the path of the target file is in a temp folder, 'C:\\Users\\Lanz\\AppData\\Local\\Temp\\tmp9h742wku\\mammal_sound_test', rather than the original absolute path and it also doesn't have the extension .ipynb. Could that info be helpful?

[timkpaine]

@Lanzzzzz this is super helpful, I think I'm relying on / instead of os.path.sep in a few places since jupyter treats paths in the unix style even on windows. I will have to go through and make sure that I normalize paths from jupyter to be windows-compliant
