If I try to update only a project avatar using **projects API**, I get a message saying "one parameter required : name, description, ..." KO: `curl --request PUT --header "PRIVATE-TOKEN: XXXXXXXXX" --form "avatar=@/tmp/test.jpg" https://xxx/api/v4/projects/XXX` OK: `curl --request PUT --header "PRIVATE-TOKEN: XXXXXXXXX" --form "avatar=@/tmp/test.jpg" https://xxx/api/v4/projects/XXX?descripton=jf` I have not tested but I think it is the same issue with **users API**.
