In the above script, in invoke stage i want to pass the lambda function main as argument, lambda function name prefixed with the gitlab branch name.
I am getting function arg syntax error.
Could someone help in finding a solution to pass the function name arg prefixed with gitlab branch name to AWS lambda invoke CLI command.

Gitlab branch name environment variable is CI_COMMIT_BRANCH https://docs.gitlab.com/ee/ci/variables/predefined_variables.html#:~:text=branches%20or%20tags.-,CI_COMMIT_BRANCH,-12.6
You don't need to create any extra variables.
invoke:
stage: invoke
script:
- aws lambda invoke --function-name "${CI_COMMIT_BRANCH}-hello-world" response.json
dependencies:
- apply
If you want to use it with variables.
invoke:
stage: invoke
script:
- func_name="${CI_COMMIT_REF_NAME}-hello-world"
- aws lambda invoke --function-name "$func_name" response.json
dependencies:
- apply
