I have a pulumi project called devops/infrastructure and I would like to create a new stack under it. But everytime I try I get this error:

Sorry, 'devops/infrastructure' is not a valid project name. project names may only contain alphanumerics, hyphens, underscores, and periods

This structure was not created by me so not sure how to add a new stack there. Any help would be appreciated

The name of that project is "elastic". It's in a repository called "devops/infrastructure".
