Basically the error was because I was using old version of aws-sdk and I updated the version so this error occured.

in my case with node js i was using <code>signatureVersion</code> in parmas object like this :

<pre><code>const AWS_S3 = new AWS.S3({
 params: {
 Bucket: process.env.AWS_S3_BUCKET,
 signatureVersion: 'v4',
 region: process.env.AWS_S3_REGION
 }
});
</code></pre>

Then I put signature out of params object and worked like charm : 

<pre><code>const AWS_S3 = new AWS.S3({
 params: {
 Bucket: process.env.AWS_S3_BUCKET,
 region: process.env.AWS_S3_REGION
 },
 signatureVersion: 'v4'
