Thanks for submitting

Fixed in #164

@Gregoirevda do you have an example of how to use the mutation response value with the updated types? We used .convertJSInputToReason(rawResult).result; in our application and now I'm not sure how to refactor to upgrade

Nvm. Figured it out. Here is a full example in case anyone else comes across the same issue

module Graphql = [%graphql
  {|
    mutation getSignedUrl($fileName: String!, $fileType: String!) {
      getSignedUrl(fileName: $fileName, fileType: $fileType)
    }
  |}
];

module Mutation = ReasonApollo.CreateMutation(Graphql);

let getSignedUrl = (mutation: Mutation.apolloMutation, ~fileName, ~fileType) => {
  let query = Graphql.make(~fileName, ~fileType, ());
  mutation(~variables=query##variables, ())
  |> Js.Promise.then_(
       (executionResponse: ReasonApolloTypes.executionResponse(Graphql.t)) => {
       let signedUrl =
         switch (executionResponse) {
         | Data(data) => data##getSignedUrl
         };
       Js.Promise.resolve(signedUrl);
     });
};

let component = ReasonReact.statelessComponent("GetSignedUrl");

[@react.component]
let make = children =>
  <Mutation>
    ...{(mutation, result) => children(getSignedUrl(mutation), result)}
  </Mutation>;
