Hi i am pretty new to kibana and elastisearch,  
we upgraded from kibana/elastisearch 7.16.3 to 8.5.2  
and since then the dashboard has been less than friendly

here is a error that has stumped us

i am assuming it has got something to do with the corresponding request , but am unable to figure out what need to be changed in the code.

help would be appreciated

Thanks and regards
