full workflow export without injected api_prompt key

[harry6661]

I get this message when I try to openwork flow at VIV_Subgraph node

Error loading input/outputs for subgraph:
Invalid subgraph file: adsfa.json
reason: full workflow export without injected api_prompt key
hint: Try loading and re exporting the workflow.

I did nothing but saved workflow via comfyui.
re exporting workflow againt didn't work for me

For anyone with this same problem in the future, instead of just using 'save as' or export, the following worked for me to fix this.

Click the top left workflow dropdown button, then click the lowest option 'Export (API)'. Then put this json file in the subnodes folder you created. Loading the file in the subgraph node should work now.
