Can't use method get_account_data

[shinraki]

Hi everybody. I mistakenly tried to send more tokens than it was on the address and now I can't check the balance by calling of get_account_data method
I get the message

Traceback (most recent call last):
File "/lib/python3.6/site-packages/iota/commands/__init__.py", line 130, in __call__
  self.response = self._execute(self.request)

iota.adapter.BadApiResponse: Bundle failed validation (``exc.context`` has more info).

How can I solve the problem?

Hey @shinraki sorry you're running into this issue.

Couple of thoughts:

• Try capturing the exception context. This is a dict that PyOTA attaches to many exceptions that can provide additional information to help debug issues:

  from pprint import pprint
  
  try:
    gad_response = api.get_account_data()
  except Exception as e:
    context = getattr(e, "context", {})
    raise
  else:
    context = None
  
  pprint(context)

• Try connecting to a different node; if the transaction is invalid, the node should not have propagated it, so you should not have any problems with other nodes.
• If you can capture the hash for the invalid bundle (you can get it easily by capturing the exception context), try contacting the node maintainer and/or posting an issue on the IRI issue tracker — I would expect that a node should drop invalid transactions after long enough.

Let me know if you are able to make any progress on this. If not, I will try reaching out to some of the IRI maintainers to see if they have any other suggestions.

Hey @todofixthis Thank you for your answer!

I forgot to say that I'm using testnet.

I got context. It says 'Transaction 1 has invalid signature (using 2 fragments).' Also now I can get bundle hash.
I tried to connect to a public testnet node: https://testnet140.tangle.works/ instead of my own local, but it didn't help. I met the same issue.
Also I contacted the node maintainer from my team, but he don't know how to drop invalid transactions. Can you help and tell how to do it?
And as I noticed our local node won't drop invalid transactions by themself after approximately 2 weeks from time when I first met this problem.
I hope for feedback

Hmm... that's curious; invalid signature. Could you post a link to the bundle on a Tangle explorer? I'm curious to see what happened.

In the meantime, I think you might be best off fetching the transactions manually. Have a look at the iota.commands.extended.utils.iter_used_addresses function. This generator will find all addresses that have transactions. You can then pipe them into the iota.commands.extended.utils.find_transaction_objects function (this will be converted into a proper API method soon) to retrieve the corresponding Transaction objects.

If you want to get the bundles, you can use the iota.commands.extended.utils.get_bundles_from_transaction_hashes function instead — basically reimplementing the GetBundles command, just without the validator (:

I used the methods described by you and now I can receive incoming transactions and bundles from seed.

But I used the method get_account_data not only to get the incoming transactions, but also to get the seed balance. If I sum up the value of the received incoming transactions it won't be a seed balance since it doesn't take into account outgoing transactions. The same applies for the method get_inputs.

If I understand this correctly. Please correct me if I'm wrong. How can I get the seed balance by ignoring the method get_account_data?

[todofixthis]

Interesting. There's only 1 input transaction in that bundle; most of the time there are 2 transactions per input (depends on the security level of the address, but it defaults to 2).

To get the account balance, you can use iter_used_addresses() in conjunction with Iota.get_balances().

[shinraki]

Thank you very much for your recommendations! I hope in the future I will be able to safely use the method get_account_data :)

Best of luck mate! Sorry for the trouble; I've logged #179 to propose a way to prevent this issue in the future.
