Hello Team,
I have created the two custom labels in my posts_controller in my rails Application
ElasticAPM.set_label(:clientid,'1')
ElasticAPM.set_label(:controller_info, params['controller'])

I can only query the clientid and not controller_info :
Here is the screenshot of the above mentioned issue
Can able to query the context.tags.clientid

Can't able to query the context.tags.controller_info

But both the tags are available in the tags section

Also, I thought of digging into Discover to figure out the issue

I figured out that ? sign near the controller_info, while itsnt present before the clientid..

How to work arround this and start working..

Thanks in advance ..

set_label

Hi Sudarshan013,

Can you please check what is the type returned by params['controller'])?

As in the documentation, it says the value can be string, nil, numeric or boolean.
