Unable to Place Batch Orders through Python

Hello,

I am trying to place 5 limit orders at a time through python, however it is giving me an error code 400 as a response when I send the request. The URL also looks to be okay after checking here.

Any idea on how I could solve this issue. Appreciate any help. Thanks
