Hey there @Freed-Wu, my sincere apologies, I somehow missed this. I can't recall why I set a default value for this, even though this has been set as a required parameter. I'm a bit out of touch w.r.t. github actions, feel free to chip in if you can think of a possible reason. I think if it's a required parameter, then it's safe to not require a default value for it in the entrypoint script.

If you'd like to go ahead with this MR, we need to make at least the following changes:

• Remove the default value entirely, not just the colon, as that will just change the name of the variable
• Remove the mention of default value of this parameter from all touchpoints: README.md, action.yml etc.

In my fork, I have changed it to

NEW_RELEASE=${GITHUB_REF#refs/tags/}
NEW_RELEASE=${NEW_RELEASE#${INPUT_TAG_VERSION_PREFIX:-v}}

And it works for me.

We should use GITHUB_REF_NAME not GITHUB_REF. document is here. GITHUB_REF is "refs/tags/$GITHUB_REF_NAME"
