Syncing won't download files from container

[vroad]

What happened?
Syncing upload files from local computer, but won't download files from container.

What did you expect to happen instead?
devspace download files from container as well.

How can we reproduce the bug? (as minimally and precisely as possible)
I tried syncing with phpfpm container

Local Environment:

• Operating System: windows
• Deployment method: helm

Kubernetes Cluster:

• Cloud Provider: none
• Kubernetes Version: Client: v1.14.3, Server: v1.15.2

Anything else we need to know?
minikube v1.3.0
devspace 3.5.12

I couldn't try 3.5.14 because both syncing and build is broken:

@vroad thanks for reporting this issue!

Regarding the fatal error in the newest version, I already fixed this and will rollout a new version pretty soon, thanks for finding and reporting this.

Regarding the sync issue, it works for me with the php:7.1.31-fpm image. Could you share your devspace.yaml?

In order for me to understand what could have gone wrong could you please also execute the following commands in two separate terminals:

• Run command devspace sync -n yournamespace --pod yourpod --container-path /remote/path/that/you/want/to/sync in the folder that you want to sync with the remote container
• Run command devspace enter -n yournamespace --pod yourpod and create a new file remotely within this shell in the --container-path you have specified

Then send the output of the first command here please.

Actually the command I used was devspace dev.
With devspace sync, sync worked as I expected. The image was php:7.2-fpm, but I doubt if the version has to do with the problem.

@vroad thanks for the output! The advantage of devspace sync is that you can see directly what the sync is doing (with devspace dev the sync log will be in .devspace/logs/sync.log but the command is essentially doing the exact same as the devspace sync command in the background). Can you provide me the sync config in your devspace.yaml?

@vroad: Does the issue still exists when using the latest version of DevSpace? If yes, please provide further details on the sync configuration within your devspace.yaml.

[vroad]

dev:
  terminal:
    labelSelector: &phpfpm-pod-selector
      app: my-app
      service: web-server
    containerName: &container-name my-app-phpfpm
  sync:
    - labelSelector: *phpfpm-pod-selector
      containerName: *container-name
      localSubPath: ./
      excludePaths:
        - .git/
        - .devspace/
        - var/

I've tried devspace version 3.5.16 and the issue still exists.
