Device Profile Codec how to use external image to decode payload?

Hi all,

I am using a tag from a company that has been acquired by another company that provides an e2e solution. I have contacted them for a decode function, but what they have provided is a docker image that would decode the payload for me.

I know briefly that the Codec page is self-contained where we can’t import any external packages, so does anyone know how I might approach using this image? Or would I be required to try decoding the message myself?

Would for example a HTTP integration be an idea, which would interact with the Docker image? The other alternative would be to reverse-engineer the decoder and then write your own JS function. There is no option to use the Docker image together with the ChirpStack Application Server codec directly.
