What happened
I orchestrate workflow with a k8s task followed by a dynamic task. When rerunning the workflow instance, the output param of the dynamic task will be applied to the k8s task, working as an environment variable in spec.template.spec.containers[0].env, with a pattern like dynamic.out(taskName). But the k8s environment variable name shouldn't contains brackets, so I got an error like this:
Message: Job.batch "00-uploader-mq-parse-7599" is invalid: spec.template.spec.containers[0].env[11].name: Invalid value: "dynamic.out(03-task-dispatcher)": a valid environment variable name must consist of alphabetic characters, digits, '_', '-', or '.', and must not start with a digit (e.g. 'my.env-name', or 'MY_ENV.NAME', or 'MyEnvName1', regex used for validation is '[-._a-zA-Z][-._a-zA-Z0-9]*').

What you expected to happen
rerunning workflow instance shouldn't occur an exception.
How to reproduce
orchestrate a workflow, with k8s task first, followed by a dynamic task.
execute workflow instance repeatedly,and the error occurs.

I orchestrate workflow with a k8s task followed by a dynamic task. When rerunning the workflow instance, the output param of the dynamic task will be applied to the k8s task, working as an environment variable in
spec.template.spec.containers[0].env, with a pattern likedynamic.out(taskName). But the k8s environment variable name shouldn't contains brackets, so I got an error like this:What you expected to happen
