stack deployment failure when using relative path

[skaneprime]

Hey there! I'm facing these error when trying to update stack via webhook. But when I'm manually redeploying it stack will deploy without error.

stack deployment failure

What may gone wrong? My fine grained personal access token is valid for authentication yet still facing this error
