Piping output into middle of bash command in 2022

Question

I am using oc command (kubectl alternative for Openshift Clusters) to get pods based on a certain condition like this:

oc get pods -n mynamespace | awk '/mypod-2022-(.)*/{print $1}'

It will give me the following output:

mypod-2022-07-01-11-23-driver
mypod-2022-07-02-11-19-driver
...

Now for each of the pod names I receive above, I need to execute the following curl command:

curl -X POST \
  'https://<my endpoint>/podDelete' \
  --header 'Authorization: Bearer token' \
  --header 'Content-Type: application/json' \
  --data-raw '{"POD_NAME": "<output>"}'

I tried following the accepted answer of this question, however xargs -i does not seem to work in 2022. So is there a way I can substitute <output> with each of the lines I receive from xargs and run the curl command?

_does not seem to work_ is not exactly a helpful error description..... — user1934428, Oct 03 '22 at 06:45

You can try this pipeline with xargs -I {}:

oc get pods -n mynamespace | awk '$1 ~ /^mypod-2022-/{print $1}' |
xargs -I {} curl -X POST 'https://<my endpoint>/podDelete' \
  --header 'Authorization: Bearer token' \
  --header 'Content-Type: application/json' \
  '{"POD_NAME": "{}"}'
