requests.exceptions.InvalidHeader: Value for header {ACCESS_NONCE: 1609705740747573} must be of type str or bytes, not <class 'int'>

[MichaelOhn]

Hi,

After following the installation step from your readme file and trying to execute the following code:

import coinbase

coinbase_api_key    = str('<api_key>')
coinbase_api_secret = str('<api_secret_key>')
coinbase = coinbase.Coinbase.with_api_key(coinbase_api_key, coinbase_api_secret)
balance = coinbase.get_balance()
print('Balance is ' + balance + ' BTC')

I get the following exception:

python3 wallet-watcher.py Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/requests/utils.py", line 868, in check_header_validity
    if not pat.match(value):
TypeError: expected string or bytes-like object

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "wallet-watcher.py", line 7, in <module>
    balance = coinbase.get_balance()
  File "/usr/local/lib/python3.6/dist-packages/coinbase/__init__.py", line 138, in get_balance

Could I have any advice of what I would be doing wrong ?

Best regards,

This is so true i just tried it now and i am getting the same error, can't i use the requests library directly

Per https://github.com/psf/requests/issues/4333#issuecomment-335677895, the python library Requests "tightened its interface to only allow header values to be strings".

An older version of Requests (e.g. 2.3.0) works, but I wouldn't recommend using it :-/

EDIT: See https://github.com/resy/coinbase_python3/compare/master...IAmADoctorYes:patch-1 for a working patch

that would not help.

for header in headers.items():
AttributeError: 'str' object has no attribute 'items'

was there ever a resolution?

No, this code is for the older API, it doesn't take into account new auth requirements documented here. If you go to the PR referenced above and check the conversation you will see some discussion that even with that fix it wont work. Someone needs to update this to the new API :-(
