I also tried the curl command and no result was returned

curl --request POST 'https://svr-kestrel.platform.simbachain.com/token' \
--header 'Authorization: Bearer MY_MASTER_TOKEN' \
--header 'Content-Type: application/json' \
--data-raw '{
  "type": "client",
}'

Expected behavior
jwt token obtained with no error

OPAL version
It's version 0.0.24 of the helm chart, but how do I check the OPAL version
