"Order placement failed: 'NoneType' object is not subscriptable"

admin

We have noticed that you are experiencing issues with our SDK due to poor error handling. The error message you are seeing, "TypeError: 'NoneType' object is not subscriptable", is a result of the SDK not handling exceptions properly. This is causing the orderResponse variable to be None, which is leading to the error you are seeing.

The correct error message from the RestAPI is "TPIN is not validated" with error code "AB4013". This error is likely being caused because you are trying to sell delivery holding without TPIN authorization. To read more about the same, please read this post on forums. (https://smartapi.angelbroking.com/topic/2376/only-pre-authoirsed-delivery-sell-orders-will-be-executed-through-smartapi-for-non-poa-clients)

Please note that our SDKs are open source, so you are welcome to make contributions to improve the error handling and other aspects of the code. Additionally, if you encounter any errors in the future, you can make a call to the RestAPI directly to get the correct error message and information on how to resolve the issue.

We apologize for any inconvenience this may have caused and thank you for your understanding.

Hello @admin

I'm receiving this error very frequently, sometimes it goes good. For example, yesterday it failed to place the order and today it was able to place the order successfully (no changes made).
I'm following up on this error from many days through multiple threads. But I never got a solution. Can you please respond or make changes as to show the proper reason for the error.

Hope I'll get some resolution this time...Thanks in advance.

Hello @admin
so here is some more info which i get while placing the order.
Basically this error is only coming while i'm trying to place order for options. For equity no error like this is coming.
Also i m getting the following details while placing order which seems to be in your api code..

File "C:\Python311\Lib\site-packages\smartapi\smartConnect.py", line 290, in placeOrder
orderResponse= self._postRequest("api.order.place", params)['data']['orderid']
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^
TypeError: 'NoneType' object is not subscriptable

So you may like to look at line no. 290 in your samrtConnect.py file for more info why this error is getting generated. Looking forward for your reply.
Thanks

@neeluru
is it working for options as well ? because i'm seeing this error only when i'm trying to place order for option {nifty, banknifty).

What i came to know that this is generating from the file smartConnect.py at line 290 which basically i don't understand. May be you can figure it out.
Let me know !!

@ksquare
in your case, I believe it's due to incorrect quantity. Please try using quantity as 50 instead of 1.
