useMutation.mutate() promise doesnt catch errors and always fulfills with undefined data

[oscmedgon]

Intended outcome:

I have a series of mutations that I need to execute in parallel at some point, and since useMutation.mutate() returns a promise I did a Promise.all, I got some errors due to mismatched variables, and the promise was fulfilled instead of rejected, and In the promise response, I got an array of undefined values, no matter if the request went wrong or it succeeds.

Actual outcome:

What I expected was to reject the promise when there are any errors, can be not passing some required variables, any error on the backend or the database.

How to reproduce the issue:

To reproduce the error you just need a mutation that it's going to fail, for example the model requires myData but is undefined.

MyComponent() {
    const [executeQuery, { data }] = useMutation(MUTATION);
    function onSendData() {
        executeQuery({variables: {myData: undefined}})
            // I'm being executed also when an error happen
            .then(console.log)
            // I'm never gonna be executed, no matter what happens
            .catch(console.error)
    }
    return(
        <h1>I'm not important<h1>
    )
}
