Problem uploading a arraybuffer to S3

Hey all! Im trying to upload a voice recording from my app to an S3 bucket. The code does the following:

1. Downloads the voice recording with axios
2. Generate a random key
3. Uploads the recording to an AWS S3 bucket

// Depending on the cloudProvider, set up the S3 client configuration
      if (options.cloudProvider === "AWS") {
        console.log("Configuring for AWS S3...");
        s3Client = new S3Client({
          region: options.iparams.recordingBucketRegionAWS,
          credentials: {
            accessKeyId: options.iparams.recordingBucketAccessKey,
            secretAccessKey: options.iparams.recordingBucketSecretKey,
          },
        });

      console.log("Fetching the file data...");
      const recordingResponse = await axios.get(options.recordingUri, {
        responseType: "arraybuffer",
      });
      const recordingFile = recordingResponse.data;

      console.log("Generating a random ID for the file key...");
      const randomId = Math.floor(Math.random() * 10000000000);
      const key = `recording-${options.ticketId}-${randomId}.mp3`;
      console.log(`Generated key for file: ${key}`);


      // try {
      //   let resint = await axios.get('http://www.google.com');
      //   console.log("Internet access is available.", resint);
      // } catch (error) {
      //   console.error("No internet access:", error);
      // }

      // try {
      //   const s3Client = new S3Client({
      //     region: options.iparams.recordingBucketRegionAWS,
      //     credentials: {
      //       accessKeyId: options.iparams.recordingBucketAccessKey,
      //       secretAccessKey: options.iparams.recordingBucketSecretKey,
      //     },
      //   });
      //  let resaws = await s3Client.send(new ListObjectsV2Command({ Bucket: options.iparams.recordingBucketName }));
      //   console.log("AWS S3 access is available.", resaws);
      // } catch (error) {
      //   console.error("Unable to access AWS S3:", error);
      // }

      const uploadCommand = new PutObjectCommand({
        Bucket: options.iparams.recordingBucketName,
        Key: key,
        Body: recordingFile,
      });

      const response = await s3Client.send(uploadCommand);

When trying to upload the file to the bucket, it throws the following error:

Error encountered during cloud upload: Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client at new NodeError (node:internal/errors:399:5) at ClientRequest.setHeader (node:_http_outgoing:645:11) at protocols.<computed>.request (/opt/framework/index.js:53:13) at /var/task/developer/node_modules/@aws-sdk/node-http-handler/dist-cjs/node-http-handler.js:72:25 at new Promise (<anonymous>) at NodeHttpHandler.handle (/var/task/developer/node_modules/@aws-sdk/node-http-handler/dist-cjs/node-http-handler.js:51:16) at process.processTicksAndRejections (node:internal/process/task_queues:95:5) at async /var/task/developer/node_modules/@aws-sdk/middleware-serde/dist-cjs/deserializerMiddleware.js:5:26 { code: 'ERR_HTTP_HEADERS_SENT', '$metadata': { attempts: 1, totalRetryDelay: 0 } } 

Thing I have already tried:

1. Double checking if all the variables and options have the correct values. This is true
2. See if I have AWS / internet access by running the commented code and accessing google / list buckets. Both these commands work!

Does anybody have a suggestion on how to fix this? Would be appreciated.
