Uncaught TypeError: Cannot read property 'attachment_error' of null

[Fabrizio Cocco]

Hi, 

We wanted to use the issue collector from Jira.

We created it, but we always get after the push of the submit button following error in the console and the modal freezes.

Hi, it is fixed in the latest Chrome version:  83.0.4103.97

I too am experiencing this (as well as other users).  Our issue collectors have been working well in the past.

If you are using Chrome, I strongly suspect it is due to the most recent update (Version 83.0.4103.61)

If I attempt to submit the issue collector while running on this version, the page hangs and eventually times out with the error you reported above.

If I use a different version of chrome, I don't see the error in the browser developer tools console, and the collector submit works.

BTW, to find the version of chrome, WITHOUT UPDATING IT, paste this in the chrome URL field:
chrome://version/

We are also running into the same thing today once chrome and edge upgrade from 81 to 83. We tried upgrade to Jira 8.5.4 and disabled SameSite by default cookies & Cookies without SameSite, as we thought it was related to this bug https://jira.atlassian.com/browse/JRASERVER-70494 but neither worked. Any other suggestions?

I am also experiencing this issue.

Also experiencing this issue as well.  Sorry I don't have a a solution.

Have found that our Jira issue collector work okay in Internet Explorer v11.535.18362.0 update version 11.0.165 (KB4530677).

I see this bug too! 

[fabricio.zeferino]

Same in here, when it will be fixed?

[James Parkes]

we are also experiencing the same issue. we've developed a feedback and bug reporting tool that uses the issue collectors for our different products. when the user submits in Google Chrome, the forms hangs until ultimately resulting in the following error...

[Christian Nytvedt]

Get it fixed, NOW!

TODAY

[Kevin Ketchum]

It looks like Chrome has provided an update to address this.

Version 83.0.4103.97 (Official Build) (64-bit)

I just tested this morning and it looks as if this version now allows issue collectors to work,

[James Parkes]

after upgrading this morning, our forms are back in action! thanks for the fix.

[Francois Dallaire]

I also confirm upgrading to Chrome 83.0.4103.97 fixes the issue.
