When I access the signed url from browser it gives a message stating "SignatureDoesNotMatch"

I checked below link but no luck.

#1976

Below is my function code

`
}).then(() => {

             const thumbFile = bucket.file(thumbFilePath)
             const config = {
               action : 'write',
               expires : '03-09-2400'
               

             }
             return Promise.all([
               thumbFile.getSignedUrl(config),
               file.getSignedUrl(config)

             ])
