Javascript aws事件错误[CredentialsError]中的Erorr:配置中缺少凭据，如果使用aws\u config\u文件，请将aws\u SDK\u LOAD\u config设置为1

我试图把一个单一的形象在aws s3桶，但每次我这样做，我得到这个错误，我已经尝试了很多，但没有工作

这是我的密码：

const dotenv = require("dotenv")
dotenv.config({ path: './config.env' })
const fs = require('fs')
const AWS = require('aws-sdk')


const bucketName = process.env.AWS_BUCKET_NAME
const awsBucketRegion = process.env.AWS_BUCKET_REGION
const awsAccessKey = process.env.AWS_ACCESS_KEY
const awsSecretKey = process.env.AWS_SECERET_KEY

const s3 = new AWS.S3({
    awsBucketRegion,
    awsAccessKey,
    awsSecretKey
})

// Upload the files to the s3 bucket 

const uploadFile = (file) => {
    console.log("This is the s3 file", file)
    const fileStream = fs.createReadStream(file.path)

    const uploadParams = {
        Bucket: bucketName,
        Key: file.filename,
        Body: fileStream,
    }
    return s3.upload(uploadParams).promise()

}


exports.uploadFile = uploadFile

下面是错误：
