/bin/bash: bad substitution

### Operating System

Windows

im getting /bin/bash: ${inputs.input_container_name}: bad substitution

**### Steps to reproduce**

**#this is custom environment which will run and execute code if i run as a job**

### Actual behavior

this is an additional issue which i resolved

please note a job is taking 1.5 hrs to schedule ..also command wise i able to register the component ..whereas if i try via yaml configuration then showing

/mnt/azureml/cr/j/46aec26067694da8a26ce7eb7e8b8875/exe/wd
azureml-logs
logs
outputs
user_logs
python: can't open file '/mnt/batch/tasks/shared/LS_root/mounts/clusters/anchestrycpucompute1/code/Users/john.athappully/data_prep_azureml.py': [Errno 2] No such file or directory

also i tried runnig your github code smple nd found same issue using yaml for training code as you use for data prepration the command wise code...i had to change to command wise for training component to make it working..
