tap-b | C implementation of Algorithm B | Learning library

I am really new to Dynamodb and NoSQL world. I am practicing AWS' GSI and LSI. I am using serverless framework. I split my handlers multiple lambda function.I want to create my data where I can see all the restaurants and what type of beers they have its' price. Also I want to query all the beers without price. I successfully create the restaurant and it's partition key is id. I can able to get all the restaurant data. But I stuck in beer logic. I create api endpoint for beers like this restaurant/{id}/createBeers, when I made post request, I got error "message": "One or more parameter values were invalid: Missing the key id in the item" because it asked for restaurant's id. I cant find the logic where i can add the restaurant's id to create the beers and how to get all beer's without price.

The Restaurant is one to many. Beer is many to many(Same name different price based on Restaurant). This is what I want to achieve.

I am trying to a script run.sh using python subprocess

The script creates a csv file and a state.json file

This is the script(works fine when i run it from terminal) :

I am trying to bridge my QEMU VM to a local adapter in my Windows 10 host, but QEMU complains that the interface name provided by ifname option to the -netdev argument cannot be opened. I have followed the answer in https://superuser.com/questions/1317652/how-to-set-up-nat-for-qemu-with-tap-backend-windows-10, but with no luck. I have cross-compiled QEMU from source to debug this behavior, for whether or not the interface name can be detected, and apparently QEMU can find the adapter's name, but not the TAP device file. To further explain my point, here's a code snippet from net/tap-win32.c:595 from the QEMU 4.2.0 source code (latest release version as of this writing), specifically tap_win32_open function, and I will highlight where it was failing in this function (look for // THIS IS WHERE IT WILL FAIL. comments):
