Cannot use a parameter variable when running docker commands

I have spent several hours trying to get the following example working

import docker

client = docker.from_env()

# using a list of image strings formatted "<registry>:<image>:<tag>"
for image in images:
    container_id = client.containers.create(image)

This results with the following error:
ERROR - 400 Client Error for http+docker://localhost/v1.48/containers/create: Bad Request ("invalid reference format")

but if I put the exact image string in place of the variable image in the above client.containers.create(image) then it works fine.

I need to be able to iterate through images for my purpose and it seems funny that I have to hard code the parameters used by API?

Any help or advice is appreciated, if this is currently possible

Start with the client.containers.create(image) entry point and reproduce the request using the reported variable-based and hard-coded image values. Inspect the actual image strings sent to Docker and compare the resulting errors; done means identifying whether the behavior is a library bug or an input-formatting issue.
