vars set with `deploy` not used by `run`

Start with the databricks bundle deploy and databricks bundle run entry points and the variable assignment sources named in the error, including .databricks/bundle/<target>/variable-overrides.json. Reproduce the two-step command sequence with a required variable and verify that a value passed to deploy is available to run without repeating --var, while preserving the required-variable error when no value is supplied.

Describe the issue

This may not be a bug but I couldn't find supporting documentation on this behavior.

When variables that do not have a default value are set with --var at deploy time, they do not carry over to run. Instead the below error is returned

Error: no value assigned to required variable <variable> ...

The variable does indeed get set in the job so I'd expect run to know the value was already set.

Configuration

Create a job that uses the below variable

databricks.yml:

bundle:
  name: dash_2

include:
  - ./resources/*.yaml

variables:
  my_variable:
    description: no default value

targets:
  prod:
    mode: production
    workspace: 
      host: <your host>
      root_path: /Workspace/Users/${workspace.current_user.userName}/.bundle/${bundle.name}/${bundle.target}

Steps to reproduce the behavior

1. run databricks bundle deploy -t prod --var="my_variable=new_value"
2. Run databricks bundle run -t prod <job_name>
3. See error

Expected Behavior

If a non-default var is set at deploy time then run will know that and pass without the var set there as well. It should act as you triggered the job from the UI.

Actual Behavior

run does not know the vars set at deploy time.

OS and CLI version

macos and ubuntu
cli v0.239.1

Is this a regression?

No
