Cube Module vs. Icinga Director - Capital letter in custom host variable prevents from modifing hosts

Unfortunately I do have a custom host variable “Location” with a capital letter at the beginning.
This wasn’t a big deal until now.
When using the Cube Module it is showing the variable with the capital “L” in the drop-down list but when selecting it it is converted to a small “L”.


When selecting “Show host status” everything is fine (hosts are displayed) but the director function is showing “Modify 0 hosts” and throwing this error when clicked:

Uncaught Error: Call to a member function hasConnection() on bool in /usr/share/icingaweb2/modules/director/library/Director/Web/Form/DirectorObjectForm.php:145
Stack trace:

#5 /usr/share/php/Icinga/Web/Controller/Dispatcher.php(7

One of my approaches would be modifying the variable to small letters directly in the Icinga Director database (2000+ hosts).
Is this a good idea?
Any other recommendations? Opening an Issue for the Cube Module?

I’ve seen that there is a new Cube Module release planned for next week (v1.2.0) but I haven’t found any open/closed issues that correspond to this error.

Thanks for your comments!

there is already an issue for this: Dimension slicing by custom data field names with certain characteristics cause failures or stacktrackes · Issue #62 · Icinga/icingaweb2-module-cube · GitHub

And it’s fixed in the master, the next release will include it.

Thanks for the quick reply! I’m sorry for missing that issue (or didn’t I get it?).
It saved my day. I’m looking forward to the next release.
