Field 'fetchResult' doesn't exist on type 'Input' while npm run dev

[ankit022023]

Hi
I am following this below link for local pickup delivery options generator with network access:
https://shopify.dev/docs/apps/functions/input-output/network-access/using-network-access

Could someone please provide insights or guidance on how to resolve this error? Any help or suggestions would be greatly appreciated.

Go into the directory for the extension and run:

shopify app function typegen

This will generate your types in api.ts and remove that error.
