Use script file in Azure Devops yaml deployment pipeline

In my build pipelines I make use of several bash scripts, references to with the Bash@3 task as below.

Now I try to use a script in a deployment, and I can't seem to find the script files. I've searched through the agent disk with tree command from several paths, even from the root, but the bash_scripts directory is nowhere to be found.

See # comments in snippet below for explanation.

A deployment job doesn't automatically checkout the source code.

Add the following task to your steps:
