template alias is already taken

[marswong]

Describe the bug
Just created a private template with the same config using a new API Key of a new project and got the error Alias is already taken.

To Reproduce
Just build a noop template with the same alias using different API keys from different projects.

Expected behavior
The template should be built successfully.

Hey @marswong , the aliases are globally unique. Any template can be made public even after creation, that's the reason for globally uniqueness.

Is it possible to change the template alias under a namespace? Assume using a docker image of node, there are several node images from different builders. And there's no template marketplace yet, it's hard for a user to know what's wrong with this error.

It's alright if there are multiple templates with the same underlying Docker image. I would recommend you to just prefix the claude-code-serve-test template alias with e.g. your namespace name or change it to something different to be unique.

If you own the namespace where the claude-code-serve-test is built, the only way to change it as of now is to rebuild the template with a new alias and deleted the old one. We're working on improving this.
