Issue with Server Object Variables

[jshankhwar-mdsol]

Having the default value of a server Object as an empty string throws the null pointer exception.
An empty string is also a string So it should be fine

servers:
url: https://hostexample{stage}.companyName{region}.{tld}{basePath}
variables:
stage:
default: sandbox
region:
default: ''
