URL: https://github.com/apache/openwhisk-composer/issues/77#issuecomment-1255822413

   I have done Openwhisk setup on multiple VMs and installed redis on 1 of the VMs with "protected-mode no". I can ping the redis instance from other VMs. But I am still getting an error when I invoke action with parallel composition. 
   ### input.json
   ```
   {
       "$composer": {
           "openwhisk": {
               "ignore_certs": true
           },
           "redis": {
               "uri": "redis://<ip.of.vm.with.redis.installed>:6379"
           }
       },
       "key":"value"
     }
   ```
   ### Error
   When I run ```wsk -i action invoke <your composition action> -P input.json```
   ```
