Error Explanation: Line: 6, Col: 28425, Error: TypeError: Cannot read property 'off' of null

Hi,
Often in visual, there is an error
Execution error
Source: URLxxx3.3.7/bootstrap.min.js, Line: 6, Col: 28425, Error: TypeError: Cannot read property ‘off’ of null.
What does it mean? Noticing it occurs in table visual.
Also following error
source: http://XXXX/static/js/arc/arc_all.js?v=4.5.0.0-1545268605, Line: 52, Col: 7980, Error: TypeError: Cannot read property ‘y_is_dim’ of undefined

And where I can find error explanation for other error.
Thank you very much.

@Stima_Livingpresent a few clarifications:

  1. Any specific steps to reproduce the error?

  2. Do the errors prevent the visuals from appearing / working properly?

  3. If you upgrade to arcadia 5.0 do the errors go away?

Hi Shaun,

  1. I will try to make some reports and see if it produces that error.
  2. Visual still can be displayed.
  3. Current version still 4.5 Arcadia Enterprise 4.5.0.0.1545268605. I am not sure when we could get it upgrade.
    Thank you very much.
