Error from the data field

post by ddev on May 28, 2020

I am getting arror from terminal that says : “built-in functions not subscriptable”.

2. If I’m passing in these arguments in the data field, must they all come in order or order not matter?

data = {

“sender”: my_address,

“receiver”: receiver,

“fee”: params.get(‘minFee’),

“flat_fee”: True,

“amt”: 0,

“first”: params.get(‘lastRound’),

“last”: params.get(‘lastRound’) + 1000,

“note”: note,

“gen”: params.get(‘genesisID’),

“gh”: params.get(‘genesishashb64’)

}

1. Can you send us the code and the full error message?
2. The order does not matter in a dict such as data.

I’ve been working around it. But here is another error I’m getting when I had to specify each parameter in the data field.

I test for the length of the addresses and it’s 58, so I’m confused.

Not sure if this is the issue, but the line:

receiver=params.get(receiver) looks funny. If params is a dict of suggested parameters returned by the API, then there is no receiver field. Did you mean to just use receiver?

Can you try to remove

receiver = params.get(receiver)

and print receiver to be sure it’s a valid address.

Note: You can copy-paste code in Forum, you just need to put them between three backquotes like ```python my python code

or ```
my result of python

It is often more convenient than images.

Yes I. Did. Perhaps I should not have right?

OK great noted. But I had explicitly specify the receiver since I want to send token from one account to another and to another account.

I’ve removed it but getting same error as WrongKeyLengthError: Key length must be 58

Can you print sender and receiver just before the line trxn = transaction... and check those are valid addresses? You can do that by copy-pasting them in an Algorand explorer such as https://goalseeker.purestake.io/algorand/testnet

post by ddev on May 28, 2020

I tried it. They’re valid addresses as shown in Image.

But if I used the full word receiver, I get this error…

This is a different error, we’re progressing.

Can you copy-paste the full code and the full reported error as a response of this post, inside a code block (i.e., between and in your post)?

There is some error being returned, but likely not in JSON which the SDK is expecting.

Can you try / catch the send_transaction statement and print the error it’ll show you what’s wrong.

For example:

try:
    tx_confirm = acl.send_transaction(signed_tx)
    print(tx_confirm)
except Exception as e:
    print(e)

Yay! It worked. @Tim that’s cool one from you. Sincerely I had used the same parameter overtime before now and it never work. Perhaps I was using it wrongly. But I learned much from the error. You really helped me a lot get over this. I almost gave up cos its been 3 days now trying to solve just one issue. But I appreciate your help a lot. Thank you and to other guys who have been helpful @fabrice @liz
