Re: [ovirt-users] Uncaught exception occurred. Cannot read property 'f' of null

[Jorick Astrego]

Got another one, when moving the SPM to another host by using the button 
in UI. It's a different error but may indicate the underlying problem...

 Please have your administrator check the UI logs

Could you install the symbol maps assocaited with the obfuscated code so
we
can get a readable stack trace. To install the symbol maps please run the
following command on the machine running the engine (or VM if it is HE).

yum install ovirt-engine-webadmin-portal-debuginfo

Please restart the ovirt-engine process with

systemctl restart ovirt-engine

after you have installed the symbol maps. Then next time you see the
message in the UI, the stack trace in the log should be readable and we
can help you better determine what is causing the problem.

right, that’s likely even easier than what I just wrote;-)

 Could you install the symbol maps assocaited with the obfuscated code so
 we
 can get a readable stack trace. To install the symbol maps please run the
 following command on the machine running the engine (or VM if it is HE).

 yum install ovirt-engine-webadmin-portal-debuginfo

 Please restart the ovirt-engine process with

 systemctl restart ovirt-engine

 after you have installed the symbol maps. Then next time you see the
 message in the UI, the stack trace in the log should be readable and we
 can help you better determine what is causing the problem.

Hi Jorick,
it’s probably not a regression, we just enabled a notification in 4.0 with 
these UI-side exceptions
You can decipher it using [1] and if you can then please post the deobfuscated 
version it would help us a lot to understand what it is. Just ~5 lines of the 
top of the stack would likely be enough

Thanks,
michal

Could you install the symbol maps assocaited with the obfuscated code so we 
can get a readable stack trace. To install the symbol maps please run the 
following command on the machine running the engine (or VM if it is HE).

yum install ovirt-engine-webadmin-portal-debuginfo

Please restart the ovirt-engine process with

systemctl restart ovirt-engine

after you have installed the symbol maps. Then next time you see the message 
in the UI, the stack trace in the log should be readable and we can help you 
better determine what is causing the problem.

[ovirt-users] Uncaught exception occurred. Cannot read property 'f' of null

[Jorick Astrego]

Hi,

We have ovirt connected to our freeipa domain. Things work fine 
generally, but once in a while I get the following error pop up in the ui:

Uncaught exception occurred. Please try reloading the page. Details:
Exception caught: Exception caught: (TypeError) __gwt$exception:
: Cannot read property 'f' of null
Please have your administrator check the UI logs

The log that goes with it:
