Handlers that serves jpg / static image not returning correct image

[isaurav0]

I want lambda function to serve png/jpg image using golang.

Steps To Reproduce Here's go.mod file.

module github.com/someone/downloader

go 1.18

require github.com/aws/aws-lambda-go v1.36.1

main.go looks like:

package main

import (
    "context"
    "encoding/base64"
    "io/ioutil"
    "net/http"

    "github.com/aws/aws-lambda-go/events"
    "github.com/aws/aws-lambda-go/lambda"
)

func handler(ctx context.Context, request events.APIGatewayProxyRequest) (*events.APIGatewayProxyResponse, error) {

    url := "https://en.meming.world/images/en/a/a1/My_Time_Has_Come.jpg"

    // download image as save it as imageBytes
    response, err := http.Get(url)
    if err != nil {
        return nil, nil
    }
    defer response.Body.Close()

    imageBytes, err := ioutil.ReadAll(response.Body)
    if err != nil {
        return nil, nil
    }

    // convert to base64 string
    imageBase64 := base64.StdEncoding.EncodeToString(imageBytes)

    // send back response
    return &events.APIGatewayProxyResponse{
        StatusCode: http.StatusOK,
        Headers: map[string]string{
            "Content-Type":                 "image/png",
            "Access-Control-Allow-Origin":  "*",
            "Access-Control-Allow-Headers": "Content-Type",
        },
        Body:            imageBase64,
        IsBase64Encoded: true,
    }, nil
}

func main() {
    lambda.Start(handler)
}

I expect it to return this image.

But I'm getting a weird image with rectangular box instead.

netlify dev is the command I'm using to run it locally.

I was told it relates to this issue in a stackoverflow post that i made.

Did you find a solution? This seems unrelated to this repository.

If you still have this issue, please report this in the Netlify CLI repository or in our support forums.

This still exists for me, I gave up on doing this in netlify.
