Update title of a card

I’m trying to update a title of a card without changing the field linked to that.

for example. in this pipe, the title field is the “ applicant's name “. but later in the process, we want to change the title to the applicant’s company name, instead of the applicant's name , and i cannot simply delete the applicant's name  and put the company name that i want, because i would lose that information

The mutation that i am using is:
“mutation{
   updateFieldsValues(input: {
    clientMutationId: "test"
    nodeId:"card id",
    values:[{ fieldId: "title" value: "New title" }]
  }) {
     clientMutationId
   }
}”

the return is:

“{
  "data": {
    "updateFieldsValues": {
      "clientMutationId": "teste"
    }
  }
}”

But the card remain with the origin title, without chance.
