Project Api Avatar field invalid

Hi everyone,

I’m having problems creating a Project via Gitlab API, I get 400 Bad request, avatar field is invalid.

According to https://docs.gitlab.com/ee/api/projects.html#create-project avatar field must get the Image File, but doesn’t clarify in which format (It says mixed). Does it need a Fileblob, a data64 image? Which is the correct format?.

Thank you very much
