Docker Synapse image crash with saml2_config section

[kallama]

This is in reference to the official matrix synapse docker image. Added the following to my homeserver.yaml file:

saml2_config:
  sp_config:
    metadata:
      remote:
        - url: https://myserver/metadata.xml

and generated the following errors when my synapse docker tries to start:

It looks like it's trying to call xmlsec1 but it doesn't exist in the docker image?
