Thanks, this is exactly the library I'm using in my project, but I get this error: so I was trying to understand how to shape the visibleApp value. Request failed with status code 409 and response { "errors" : [ { "id" : "96762428-38c5-45c5-a700-fadd798fe012", "status" : "409", "code" : "ENTITY_ERROR.RELATIONSHIP.INVALID", "title" : "The provided entity includes a relationship with an invalid value", "detail" : "The relationship 'visibleApps' expects data as an array but an object was given.", "source" : { "pointer" : "/data/relationships/visibleApps" } } ]}).
