[Error] function "slice" not defined -- Which version of docker is supported?

[thorntonmc]

I'm using distrobox 1.5.0 with Docker. Per the documentation here https://distrobox.privatedns.org/compatibility/#supported-container-managers

I believe I'm using a valid version of docker

$ docker version
Client: Docker Engine - Community
 Version:           19.03.5
 API version:       1.40
 Go version:        go1.12.12

 Experimental:      false

Server: Docker Engine - Community

 docker-init:
  Version:          0.18.0
  GitCommit:        fec3683

However I get errors related to formatting options.

$ distrobox enter my-container
Template parsing error: template: :2: function "slice" not defined
Cannot find container my-container
Create it now, out of image registry.fedoraproject.org/fedora-toolbox:38? [Y/n]: ^C

If i take that formatting option out, everything works fine. Just curious if the docs need to be updated and newer versions of docker are required?

which host OS are you running. as 19.03 ran out of support 2 1/2 years ago, I would look into getting a newer docker version.

Thank you!
