unable to read variable using env/strenv in a select

[traghu84]

I have my yaml as below.

name: "MicroService"
server:
type: 'Apache'
names:
- 'ROW1'
- 'ROW2'
- 'ROW3'
- 'NAFTA1'
- 'NAFTA2'
- 'NAFTA3'

When i run this command below directly, i get the proper output.
yq '.server.names[] | select( . != "ROW" )' configs.yaml
output:
NAFTA1
NAFTA2
NAFTA3

But if do the same by storing the select condition into a variable, its not working as expected.
REGION='. != "ROW"'
yq '.server.names[] | select(strenv(REGION))' configs.yaml
output:
ROW1
ROW2
ROW3
NAFTA1
NAFTA2
NAFTA3

I tried using env as well, but the result is same.
By the way i am running this from a bash in jenkins pipeline.
Am i doing something wrong here? Can someone please help, this is the final step for completing my work.

strenv will read the variable as a string - looks like you want to evaluate that string as an expression - try eval(strenv(REGION)) see https://mikefarah.gitbook.io/yq/operators/eval#dynamically-update-a-path-from-an-environment-variable for an example
