MaxFileSizeUploadError can't be caught and crashes the server

Hi!

I have a problem with a custom middleware and the use of the processRequest function. Here is my custom middleware:

try {
    return processRequest(request, options)
                    .then(body => {
                        console.log("body is : ", body);
                        ctx.request.body = body;
                        return next();
                    })
                    .catch(error => {
                        console.log("Error catched : ", error);
                        if (error.status && error.expose) response.status(error.status);
                        return next(error)
                    });
} catch (error) {
    console.log("Error catched bis : ", error);
}

If I try to upload a file bigger than the allowed limit, I get the following error and my app crash.

events.js:137
      throw er; // Unhandled 'error' event
      ^

MaxFileSizeUploadError: File truncated as it exceeds the size limit.
    at FileStream.file.stream.once (/Volumes/lake/projects/evibe/api-lovejs/node_modules/apollo-upload-server/lib/middleware.js:35:13)
    at Object.onceWrapper (events.js:255:19)
    at FileStream.emit (events.js:160:13)

I can’t capture the error. Any idea?

Thanks 😃

I have the same problem, in my case file stream throw error and not exist handlers for that error.

Solution in my case: wrap stream in promise

export const resolvers = {
  // ... other resolvers ...
  Mutation: {
    uploadImageResolver: async (_, { image }) => {
      // throwing error
      await new Promise(async (res, rej) => {
        const { createReadStream } = await image;
        const stream = createReadStream();
        stream.on("error", (err) => {
            rej(err);
        });

        // ... some code about using that stream, like save file ...
        // await saveFile(stream);
        res(); // success
      });
    },
  },
};
