I use tonsdk under apps in the warehouse to apply it to my own wallet framework code. If there is a problem with the generated transaction signature, an error will be reported.

When I applied the ton SDK in core/src/apps/ton in the warehouse to our hardware wallet framework for use, the boc request https://toncenter.com/api/v2/sendBoc of the ton transaction information generated by sign_message.py in the SDK was broadcast, and it would prompt: {'ok': False, 'error': 'INVALID_BAG_OF_CELLS: bodyinvalid bag-of-cells failed to deserialize cell #1 [Error : 0 : invalid index entry [116; 53], [data.size():169]]', 'code': 500}, and when the boc = bytes(signing_message.to_boc()) returned by the create_transaction_digest method in _wallet_contract.py was changed to boc = bytes(signing_message.to_boc(False)), when broadcasting again, the error message would become: {'ok': False, 'error': 'INVALID_BAG_OF_CELLS: bodyinvalid bag-of-cells failed to deserialize cell #1 [Error : 0 : invalid index entry [116; 53], [data.size():169]]', 'code': 500}. 'error': 'LITE_SERVER_UNKNOWN: cannot apply external message to current state : External message was not accepted\nCannot run message on account: inbound external message rejected by transaction FCBC39F68D71AE15B42A0E6A5DFAB4D5AA70A2BD3D5A54B7679976DDB6040BFC:\nexitcode=33, steps=23, gas_used=0\nVM Log (truncated):\n...te NOW\nexecute LEQ\nexecute THROWIF 36\nexecute PUSH c4\nexecute CTOS\nexecute LDU 32\nexecute LDU 32\nexecute LDU 256\nexecute LDDICT\nexecute ENDS\nexecute XCPU s4,s3\nexecute EQUAL\nexecute THROWIFNOT 33\ndefault exception handler, terminating vm with exit code 33\n', 'code': 500}, do you know what the reason is?
