Multiple Inputs do not work inside parallel inside Blue Ocean inside declarative when using when condition returning false for one stage
The issue is that inside Blue Ocean, when this is the case, there are no prompts for input steps presented to the user.
Also, the console output in Blue Ocean shows the input step, but you are unable to select anything.
This does not happen when exiting Blue Ocean.
Expect to be prompted for input steps in Blue Ocean UI.
The below demonstrates a scenario where 2 input steps are defined inside a parallel block. In this case the when block will return true for one stage and false for the other.
Removing parallel fixes it.
Also, if you change
then it works. So, it works sequentially.
