TypeError: _encrypt() got multiple values for argument 'recipients'

[devorbit]

Hi All!
I am getting one error where I am trying to do encrypt a file with the following command but its showing error even though I am passing argument recipient one time. Please help me on the same.
rkey: str = 'test_key_id'

with open('my-unencrypted.txt', 'rb') as f:
status = gpg.encrypt(
data=f,
recipients=rkey,
always_trust=True,
output='encrypted.txt.gpg')

For rkey I also tried
rkey = str(imported_keys.fingerprints[0])

but nothing is working and I am getting error like
status = gpg.encrypt(
File "<base_path>\venv\lib\site-packages\gnupg\gnupg.py", line 1064, in encrypt
result = self._encrypt(stream, recipients, **kwargs)
TypeError: _encrypt() got multiple values for argument 'recipients'

I believe recipients is supposed to be a list or tuple.
