I want for forEach function to complete before returning results, how do you do this? The function returns null in all results when I return code because it doesn't wait for forEach to end, so how do i solve this?

async function fileResult(fileCard, userId, req, fileTypes) {
  if (req.files && Object.keys(req.files).length) {
    let resultObj = {
      smallResult: null,
      mediumResult: null,
      largeResult: null,
      thumbnailResult: null,
    };

    const result = fileTypes.forEach(async (fileType) => {
      if (req.files[fileType]) {
        try {
          const fileUploadResult = await uploadFile(fileCard, userId, req, fileType);

          if (fileType === 'small') {
            resultObj['smallResult'] = fileUploadResult;
          } else if (fileType === 'medium') {
            resultObj['mediumResult'] = fileUploadResult;
          } else if (fileType === 'large') {
            resultObj['largeResult'] = fileUploadResult;
          } else if (fileType === 'thumbnail') {
            resultObj['thumbnailResult'] = fileUploadResult;
          }

          if (!fileUploadResult.success) {
            console.log(fileUploadResult.error, 500);
            return;
          }

          // console.log(resultObj);
        } catch (err) {
          console.log(err);
        }
      }
    });

    return resultObj;
  }
}
