I am using github actions workflow for code deployment. One of the flow is manual using workflow_dispatch. I am able to select main or any feature branch but when i select tags - most of them are disabled and gives you below error message:
"Workflow does not exist or does not have a workflow_dispatch trigger in this tag. Learn more about manual workflows"
If I create a new git tag, i am able to deploy. Please help me by sharing the logic and reasoning. Thanks,
If workflow didn't exist when the tag was created, it's not available. The same goes for branches.
The way to fix it is to either cherry-pick workflow there and move a tag or re-base the tag on top of the master branch.
Also keep in mind if you modify workflow on your master branch, but you have a different version in branches - it will use the branch / tag version.
If you want to keep 1 version across all tags - you should pass a tag as an input variable and run it on master branch instead of running workflow on this tag. Then you just have to modify your checkout-action to checkout the passed tag, not leaving it with defaults.
