NamespaceApi->set_acl: The namespace name is missing from the URI.

[MartinsMessias]

I'm trying to use the set_acl method, but I'm getting an error even though I'm sending the data correctly (or at least I think I am).
Below is an example of the code and its output.

import isi_sdk_8_2_1
from isi_sdk_8_2_1.rest import ApiException
from pprint import pprint
from backend.settings import api_namespaces


def sdk_test():
    namespace_path = "/ifs/isilon8201/lab8201/smb/textosmb.txt"  # str | Namespace path relative to /.
    acl = True  # bool | Update access control lists.
    namespace_acl = isi_sdk_8_2_1.NamespaceAcl(
        authoritative="mode",
        group=isi_sdk_8_2_1.MemberObject(
            name="Guests",
            type="group"
        ),
        action="update",
        mode="0775",
        acl=[],
        owner=isi_sdk_8_2_1.MemberObject(
            name="Guest",
            type="user"
        )
    )

    try:
        api_response = api_namespaces.set_acl(namespace_path=namespace_path, acl=acl, namespace_acl=namespace_acl)
        pprint(api_response)
    except ApiException as e:
        print("Exception when calling NamespaceApi->set_acl: %s\n" % e)
    
        
sdk_test()

Output:

I solved this error just commenting a part of the code inside isi_sdk_8_2_1/api_client.py. Lines: 128 - 146

           replacement = path_params[0][1] # Added by me
           for k, v in path_params:
               v_str = str(v)
               # Check for the special case of the
               # x-isi-url-encode-path-param, which indicates that the
               # parameter should be encoded with quote_plus in order
               # to encode the '/' character.
               # check if the first part of v_str matches the tag
               # if v_str[:self.quote_plus_tag_len] == self.quote_plus_tag:
               #     # remove "__x-isi-url-encode-path-param__"
               #     v_str = v_str[self.quote_plus_tag_len:]
               #     # then url-encode with quote_plus
               #     replacement = quote_plus(v_str)
               # else:
               #     replacement = quote(v_str, safe=config.safe_chars_for_path_param)

               # specified safe chars, encode everything
               resource_path = resource_path.replace(
                   '{%s}' % k, replacement)

When I make these changes the method starts to work correctly. What makes me believe that this part of encoding the '/' is causing this error.
Can you tell me something about it? Can they solve it or am I wrong?

Does it work (without modification to isi_sdk_8_2_1) if you omit the first /?

namespace_path = "ifs/isilon8201/lab8201/smb/textosmb.txt"  # str | Namespace path relative to /.

The first part (ifs) can be confusing because it is actually a namespace name followed by a path under that namespace (i.e. not a filesystem path). For example, I believe you could make another namespace, foo, which points to /ifs/foo. Then, you could have

namespace_path = "foo/isilon8201/lab8201/smb/textosmb.txt"

and that would affect /ifs/foo/isilon8201/lab8201/smb/textosmb.txt.

Thank you so much for replying! That was exactly it. I had tried it before but got another error, but now I know it was caused by another error in my code.
