Why modify_permission doesn't work?

[IIMars]

Hello, I encountered some problems when I used python-gvm, so I would like to ask you for advice.
When I use modify_permission to modify an existing permission, it doesn't work as expected.

1. When I passed in the permission_id and comment values, it did not successfully modify the comment corresponding to the permission, but reported an error: <modify_permission_response status="400" status_text="Error in SUBJECT">
   The code shows as below:

path = '/run/gvmd/gvmd.sock'
connection = UnixSocketConnection(path=path)
with Gmp(connection=connection) as gmp:
    gmp.authenticate('admin','199954')
    print(gmp.modify_permission(
        permission_id='d140d640-01f1-4c98-8fe8-616e8829e55d',             #The id of authenticate
        # name='authenticate',
        comment='010203040000',
        # resource_type=EntityType.SCAN_CONFIG,
        # resource_id='d21f6c81-2b88-4ac1-b7b4-a2a9f2ad4663',
        # resource_type=None,
        # resource_id=None,
        # subject_id='c3de57e6-6678-4a06-9866-47e43321fa77',             #The id of an USER
        # subject_type=PermissionSubjectType.USER
    ))

2. When I passed in the subject corresponding to the permission, it reported another error: "gvm.errors.GvmError: Remote closed the connection"

path = '/run/gvmd/gvmd.sock'
connection = UnixSocketConnection(path=path)
with Gmp(connection=connection) as gmp:
    gmp.authenticate('admin','199954')
    print(gmp.modify_permission(
        permission_id='d140d640-01f1-4c98-8fe8-616e8829e55d',             #The id of authenticate
        # name='authenticate',
        comment='010203040000',
        # resource_type=EntityType.SCAN_CONFIG,
        # resource_id='d21f6c81-2b88-4ac1-b7b4-a2a9f2ad4663',
        # resource_type=None,
        # resource_id=None,
        subject_id='c3de57e6-6678-4a06-9866-47e43321fa77',             #The id of an USER
        subject_type=PermissionSubjectType.USER
    ))

3. Only when all the parameters are passed in can the modification be successful.But I don't know what parameter should be passed in those permissions don't have Resource.
