We use the plugin _block_configurable_reports (_version 3.7.0 2019060300) with Moodle 3.5.6+ (Build 20190628). Theme Boost. If i try to use a template for a request it will show the word "Array" instead of the result.  Example:

select u.id from prefix_user u
where u.id < 10

My template is as simple as :

Record template   idnumber is [[id]] 

And the output shows:

Trial request
Total record count = 9

ArrayArrayArrayArrayArrayArrayArrayArrayArray

End or page
