How to set one specify account can update Smart Contract?

Hi everyone,

Account A has reached 10 apps, so I can’t use this account to create more apps.
I use the new Account B to create a new app, it’s ok.
But I want to use account C - this is the specified account in my question and I want to use this account to grant permission to update my app (was created by account A and account B)

This is my TEAL code:

#pragma version 2

byte "msig"
txna ApplicationArgs 0
app_global_put

byte "OwnerPercentage_1"
txna ApplicationArgs 1
btoi
app_global_put
byte "OwnerAddress_1"
txna ApplicationArgs 2
app_global_put

txn OnCompletion
int UpdateApplication
==
bnz handle_updateapp

handle_updateapp:
// This is the specified account I want to use to grant permission to update apps on many accounts
addr 2VQO54JD7VXV7QAHPUFYJD4ZLRA3Z7WR6WYBQEREQBI6ZWHSF5VES4FEHQ
txn Sender
==
return

int 1
return

I got the error message when I create the app:

{"message":"TransactionPool.Remember: transaction V6GE5TKVUMUBVK64TIAU3LQZJKKPEEGYYG56YTD5F4SXZUJCFMOQ: transaction rejected by ApprovalProgram"}

I think my error is because I use another account to create an app (different account 2VQO54JD7VXV7QAHPUFYJD4ZLRA3Z7WR6WYBQEREQBI6ZWHSF5VES4FEHQ). But I don’t know how to resolve my problem.

Anyone can help me, please!

You can debug your code to see where it goes wrong:

My guess is that you did not add application args to your update call, and the program crashes at the beginning txna ApplicationArgs 0.

Thank for your response.

My guess is that you did not add application args to your update call, and the program crashes at the beginning txna ApplicationArgs 0 .

This is my transaction to create the app and I added application args. If I change this code

handle_updateapp:
// This is the specified account I want to use to grant permission to update apps on many accounts
addr 2VQO54JD7VXV7QAHPUFYJD4ZLRA3Z7WR6WYBQEREQBI6ZWHSF5VES4FEHQ
txn Sender
==
return

to

handle_updateapp:
int 1
return

then the transaction is created successfully.

Besides, I tried to use tealdbg to debug my code but I got the error:

./tealdbg debug myprogram.teal

and this is my code:

#pragma version 2
byte "msig"
txna ApplicationArgs 0
app_global_put

byte "admin"
txn Sender
app_global_put

byte "OwnerPercentage_1"
txna ApplicationArgs 2
btoi
app_global_put
byte "OwnerAddress_1"
txna ApplicationArgs 3
app_global_put

txn OnCompletion
int UpdateApplication
==
bnz handle_updateapp

handle_updateapp:
addr 2VQO54JD7VXV7QAHPUFYJD4ZLRA3Z7WR6WYBQEREQBI6ZWHSF5VES4FEHQ
txn Sender
==
return

int 1
return

To debug stateful smart contracts, you need to add context:
