Graylog 3 error when trying to create new sidecar configuration - Cannot read property 'then' of undefined

[daniejstriata]

Hi,

I’m using a reverse proxy to access the graylog frontend and upgraded from 2.5.2 to 3.0.1. on Centos 7.6. I was testing 3.0.1 before I upgrade the rest and got stuck browsing to
https://example.com/system/sidecars/configuration/new
to create a new sidecar configuration. (Was also trying to import legacy configuration but nothing seemed to happen from there when I clicked the button.)

I don’t see anything in the server or nginx log files when this happens.

( It is related to the other issue I reported:
Graylog 3 error when trying to create new sidecar configuration - v.all(…) is undefined )

Gives me this error:

Cannot read property ‘then’ of undefined

Stack Trace:

TypeError: Cannot read property ‘then’ of undefined

Would it maybe make sense to post what your sidecar configuration is and how its set up??

[daniejstriata]

I cannot create the configuration. I get the error. I do have working legacy configurations though but I cannot convert it to the new one. When I click the button nothing happens.

One possibility - browser cache. Graylog uses it a lot and upgrades fail oddly if you try and use the same page on the upgraded version. Usually closing the tab and opening a new one to the console works but clearing the browser cache will make sure.
