Description
Prerequisites
- I am running the latest version of ComfyUI
- I have searched existing issues to make sure this isn't a duplicate
- I have tested with all custom nodes disabled (see how)
What happened?
Expected: Workflow should load even if specific custom node(s) are not installed, while displaying the appropriate dialogue about the missing custom node(s).
Actual: The workflow does not load at all, although the correct dialogue for the missing custom node(s) is shown.
Steps to Reproduce
- Make sure not to have Comfy-Deploy (https://github.com/BennyKok/comfyui-deploy) and ComfyUI-Omini-Kontext (https://github.com/tercumantanumut/ComfyUI-Omini-Kontext) installed.
- Attempt to drag and drop both/either of the workflows.
- Notice the correct dialogue pop-up, but the workflow(s) not importing.

Additional Context
Workflows load correctly if the required custom node(s) are already installed before importing. However, if a workflow was previously loaded and the custom node(s) are uninstalled afterward, ComfyUI can still launch that workflow successfully on startup, since it reloads the last saved session.
