Custom dependencies ZeroGPU Space

Im trying to install custom dependencies in a zerogpu space: https://huggingface.co/spaces/Hommes/lets-chat-langchain-zerogpu. However the requirements from the requirements.txt are never run. If I ssh into the instance I can install the required packages so it looks to be a setup error from Huggingface.

I have initiated a blank gradio app template and then pushed a new requirements.txt file to the space and performed a factory rebuild.

For non ZeroGPU spaces I see this step in the build which I dont see in the ZeroGPU build:
RUN --mount=target=/tmp/requirements.txt,source=requirements.txt pip install --no-cache-dir -r /tmp/requirements.txt

Looks to have been resolved think the problem was transient
