WLST importMetadata() fails with Unable to load MDS configuration from "META-INF/adf-config.xml"

I am trying to import MDS data to an Oracle system using WLST and the function importMetadata().

The system is configured as as follows:

AdminSServer
infra_server1  - (infra_cluster_1)
infra_server1  - (infra_cluster_1)
infra_server1  - (infra_cluster_1)

soa_server1  - (soa_cluster_1)
soa_server2  - (soa_cluster_1)
soa_server3  - (soa_cluster_1)

Remotely I have tried suing the following script:

import wlimport os
import time
import sysprint("*** Connecting ***")
connect("weblogic", "password", "t3://10.10.11.12:7001")try:
    domainConfig()
    print("-"*100)
    path="D:\\tmp\\soa-mds.jar"
    print("*** calling importMetadata(path='%s') ***" % path)
    importMetadata(application='soa-infra',
                   server='AdminServer',
                   fromLocation=path,
                   docs='/apps/**',
