Following is dummy program demonstrating the issue -

def a(args, stdout=None, stderr=None):
    print('running a()')
    print(f'args - {args}')
    print(f'stdout - {stdout}')
    print(f'stderr - {stderr}')

def b(*args, **kwargs):
    print('running b()')
    stdout = kwargs.pop('stdout', 'efgh')
    a(args=args, stdout=stdout, **kwargs)

b('abcd')
b(args='abcd', stdout='efgh')

Here's the output -

running b()
running a()
args - ('abcd',)
stdout - efgh
stderr - None
running b()
Traceback (most recent call last):
  File "temp.py", line 13, in <module>
    b(args='abcd', stdout='efgh')
  File "temp.py", line 10, in b
    a(args=args, stdout=stdout, **kwargs)
TypeError: a() got multiple values for keyword argument 'args'
