I am building comments for articles (articlefeedback Collection Type). I am able to add the users using the Strapi Users inteface, however, I am trying to replicate the same behavior with my Frontend application and the Mutation to add the relation field fail as Bad request. What I am doing wrong? Thanks in advance for your help.

Mutation Fail

mutation updateArticlefeedback($id: ID!, $usrliked: ID!) {
updateArticlefeedback(id: $id, data: { usrliked: { data: { attributes: { username: $usrliked }}}} ) {
data {
id
attributes {
liked,
nlikes,
usrliked {
data {
id,
attributes {

Are you sure userliked is ID type?

@viac92 Thanks! Based on your question, I realized that I have to pass “usrliked” as an Array. If I send the Mutation with no “usrliked” parameters the record get inserted with an empty array. Now, I am trying to figure out how to pass an array in the query variables. I have tried with $usrliked: Array! but GraphQL respond with error “Unknown type “Array”.” - The error message change if I define $usrliked as Int!, or ID! or String! → “message”: “Variable “usrliked” of type \Int!” used in position expecting type “[ID]”." - Do you know how to pass an array in Query Variables?

I’m not sure but try to set the userliked var like this userliked: [ID] or with ! if is non-nullable.
