PATCH method not allowed for Storage Services REST API "Path - Update"

I try to use the Set Access Control option described in https://zcusa.951200.xyz/en-us/rest/api/storageservices/data-lake-storage-gen2?view=rest-storageservices-datalakestoragegen2-2019-12-12.

Although I was able to run other methods (as Path - List) it seems that just "GET,HEAD,PUT,DELETE" methods are "allow" as the answer headers show (see hardcopy) and I am receiving a 405 error.

Please, does someone have any suggestion?

    "Self solved": I have to use the DNS suffix for the Azure Data Lake Storage endpoint and not the blob one. I mean dfs.core.windows.net and not blob.core.windows.net.

    Now the error is "400 The access control list value is invalid", but this is other history...

    The error “400 The access control list value is invalid” typically indicates that there might be a problem with the format or values you’re using in the ACL. Please ensure you have updated the ACL entries in correct format and assigned the necessary permissions to the user.
