[BUG]: Metadata not included in output image

[Memesphere]

Describe the bug

• I deployed a runpod endpoint worker based on runpod/worker-comfyui:5.1.0-flux1-dev
• I POSTed a test workflow based on test_resources/workflows/workflow_flux1_dev.json
• I received a SUCCESS response including the base64 encoded PNG
• I wrote the PNG to my local machine (see attached)
• I inspected the image using exiftools

Expected behaviour

By default, Comfyui embeds the workflow into the output image.
I was expecting the output image to include the submitted workflow as metadata

Versions (please complete the following information):

• Docker version: 5.1.0

Additional context

FYI: I tried building a custom image with this Dockerfile and it worked for me.

FROM runpod/worker-comfyui:5.2.0-base

RUN sed 's/ --disable-metadata//g' -i /start.sh
RUN sed 's/payload = {"prompt": workflow, "client_id": client_id}/payload = {"prompt": workflow, "client_id": client_id, "extra_data": {"extra_pnginfo": {"workflow": workflow}}}/' -i /handler.py
