beneficiaries: missing posting authority ?

[fxnormaluser]

The beneficiaries argument in post doesn't work for me.

steembase.exceptions.RPCError: 3030000 tx_missing_posting_auth: missing required posting authority

I'm using a dictionary for beneficiaries like this:

[{'account': 'account1', 'weight': 5000}, {'account': 'account2', 'weight': 5000}]

Even if I set only the posting account as beneficiary, it returns the same error.

[Netherdrake]

Your usage is correct.

The json data structure steem-python generates seems to be correct, however the bytes output that goes into transaction signing is not, hence the missing authority error.

This suggests there might be a bug somewhere in the serializer, perhaps in regards to composition of the StaticVariant > Array > Map types.

Some solution in sight?

[fxnormaluser]

I just found out, how it works.

This doesn't work:

[{'account': 'account1', 'weight': 5000}, {'account': 'account2', 'weight': 5000}]

This works:

from collections import OrderedDict
[OrderedDict('account': 'account1', 'weight': 5000), OrderedDict('account': 'account2', 'weight': 5000)]

[fxnormaluser]

Actually it still doesn't work :/

@Netherdrake

Hi, Is there any update about this issue?
I encountered the same problem when I tried to post comment with beneficiaries.

Thank you.

[KylePiira]

The issue is still present I'm going to check to see if piston has some way of solving this.

I had the same issue for SteemJ and I can confirm @Netherdrake theory - For me it was related to the byte representation.

You can check my implementation of the byte transformation starting with the toByteArray method of the CommentOptionsOperation and the CommentPayoutBeneficiaries

I hope that helps a little bit :/

Best regards,

Until this issue is fixed in steem-python you can use piston like so:

from piston import Steem
s = Steem(keys=[private_posting_key])
s.post(
    title="This is a Test Post",
    body="Hello World this is a test post.",
    author="username",
    meta={
        'extensions': [[0, {
            'beneficiaries': [
                {'account': 'beneficary_account_username', 'weight': 5000},
            ]}
        ]]
    },
    tags=['spam','test']
)

Still not fixed.

Tried the piston workaround but it doesn't allow me to use other parameters like tags or app.

Would like to see this fixed in this library so that I can fully rely on this library.

the following did the trick for me. This is basically copying piston code parts into steem-python. Thanks @KylePiira for the pointer to piston!

in combination with

ops = [operations.CommentOptions(

       "max_accepted_payout": "1000000.000 SBD",

                {'account': beneficiary, 'weight': weight},
            ]}]]
    }
)]

This is clearly not a fix, but a workaround. And I'm not sure if it would work with more than one beneficiary...

[moisespr123]

Thanks @crokkon! It worked but what I did was to manually added the beneficiary in the ops code you posted below. I think if that structure is followed, it should work with more than one.

[emre]

I can confirm @crokkon's workaround works for multiple beneficiaries.
