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 signatureVersion in parmas object like this :
const AWS_S3 = new AWS.S3({
params: {
Bucket: process.env.AWS_S3_BUCKET,
signatureVersion: 'v4',
region: process.env.AWS_S3_REGION
}
});
Then I put signature out of params object and worked like charm :
const AWS_S3 = new AWS.S3({
params: {
Bucket: process.env.AWS_S3_BUCKET,
region: process.env.AWS_S3_REGION
},
signatureVersion: 'v4'
});
