Does the Event Hub Consumer Group have to be lowercase?

[elKei24]

Hi, we are using the Azure Event Hub trigger using the blobMetada strategy. We noticed that for one consumer group the scaling did not work, and found out that KEDA was unable to find the checkpoint blob. The reason is this line, that converts the consumer group name section of the blob name to lowercase, while our consumer group was camelCased.

I was thinking of adding a note to the docs, stating that only lowercase consumer groups are supported. On the other hand, I do not understand the reason for this limitation, maybe removing the conversion to lowercase could be an option as well? Can someone explain if/why the ToLower-call is required?

Maybe @JorTurFer? I've seen that you've been the working on that part.

Hi,
TBH I have no idea, but maybe @SpiritZhou has any insight about if this is something related with eventhub service or just something that we can remove
