Api empty project snippets
What does this MR do?
Ensures that code content is not empty. The PUT request returned a 500 error if code was empty. The POST endpoint worked differently: here a validation in the model catched the error. However, I added a validation in the API to unify the error message (error code is still the same: 400).
What are the relevant issue numbers?
