SteemConnect: Unable to sign a custom_json operation with an active key

Project Information

• Repository: https://github.com/steemit/steemconnect
• Project Name: SteemConnect

Expected behavior

I was expecting to be able to sign a custom_json operation with an active key the same way I sign a custom_json with a posting key via the tool https://steemconnect.com/sign/

Actual behavior

When we fill out the field "Required Auths" with the account name and sign the transaction with an active key we should be able to broadcast the custom_json operation without having to enter any data in the Required Posting Auths field.

How to reproduce

- go to https://steemconnect.com/sign/
- select Custom Json
- fill in the Required Auths field with your account name this way: ["accountName"]
- leave the field Required Posting Auths empty (as it is only required when using a posting key not an active key)
- fill in the Id field with "test"
- fill in the json fiels with { "test": "test" }
- click Generate Link
- click Try Link
- click Continue
- enter the account name in the Username field
- enter the active key of the account in the Password or key field
- finally click Sign in

The following error appears:

By checking the developer console I can see that the wrong operation is trying to be broadcasted:

Current operation brodcasted:

[
    "custom_json",
    {
        "required_auths": [
            "accountName"
        ],
        "required_posting_auths": [
            "accountName"
        ],
        "id": "test",
        "json": "{ \"test\": \"test\"}"
    }
]

Operation that should be broadcasted (empty array in required_posting_auths item):

[
    "custom_json",
    {
        "required_auths": [
            "accountName"
        ],
        "required_posting_auths": [],
        "id": "test",
        "json": "{ \"test\": \"test\"}"
    }
]

So, if nothing is entered in the Required Posting Auths field, an empty array should be sent not a copy of the Required Auths field value.

A workaround works though, fill out the field Required Posting Auths with an empty array [] will send an empty array when the transaction is broadcasted and you won't get any error.
