amazon web services - Strapi S3 SignedUrl

Question

uploading files from strapi to s3 works fine. I am trying to secure the files by using signed urls:

var params = {Bucket:process.env.AWS_BUCKET, Key: `${path}${file.hash}${file.ext}`, Expires: 3000};
      var secretUrl = ''
      S3.getSignedUrl('getObject', params, function (err, url) {
        console.log('Signed URL: ' + url);
        secretUrl = url
      });

      
      S3.upload(
        {
          Key: `${path}${file.hash}${file.ext}`,
          Body: Buffer.from(file.buffer, 'binary'),
          //ACL: 'public-read',
          ContentType: file.mime,
          ...customParams,
        },
        (err, data) => {
          if (err) {
            return reject(err);
          }

          // set the bucket file url
          //file.url = data.Location;
          file.url = secretUrl;
          console.log('FIle URL: ' + file.url);

          resolve();
        }
      );

file.url (secretUrl) contains the correct URL which i can use in browser to retrieve the file. But whenever reading the file form strapi admin panel no file nor tumbnail is shown. I figured out that strapi adds a parameter to the file e.g ?2304.4005 which corrupts the get of the file to AWS. Where and how do I change that behaviour

Help is appreciated
