Lambdas reutrn images with Go

I am trying to return an image from my lambda function

Here is my return. code:

// Your server-side functionality
return &events.APIGatewayProxyResponse{
	StatusCode: 200,
	Headers: map[string]string{
		"Access-Control-Allow-Origin":  "*",
		"Access-Control-Allow-Headers": "Content-Type",
		"Content-Type":                 "image/png",
		"Content-Length":               fmt.Sprintf("%d", len(b64img)),
	},
	Body:            b64img,
	IsBase64Encoded: true,
}, nil

I did profile the Body with a Curl request, so there is a return value. I have read that this is a known bug on Netlify, is there a workaround?

I still get the broken image from the browser

What’s the name of the function handling this and how can we reproduce the issue? I see many functions on that site.

I have been running it locally, here is the endpoint and the error:

https://hokr.xyz/.netlify/functions/Image

Here is the current error:

This function has crashed

An unhandled error in the function code triggered the following message:

FormatError - png: invalid format: invalid image size: 0x0

Connection details

Netlify internal ID: 01H1SJA9MDDYQ7X719WR2KEBY7

I have tracked it down to the referenced images in my go func.

How do I access images in my public folder via file path from Go?

1000×976 43.2 KB

is stored here:

/public/backgrounds/eye.png

But I don’t know how to reference that from my gocode.

I now have the component parts stored in my serverless function directory, still not referencing the images.

From what I can tell, the issue is my graphics lib.
