Variable Replacement

Variables in module input fields are replaced following the standard Jinja templating rules, here are some examples:

Comment on source valueSource value (exact value of x)Body to be replacedFinal resultComment on final result

Comment on source value	Source value (exact value of x)	Body to be replaced	Final result	Comment on final result
null value	null	{{ x }}	null	null value
string	hello	{{ x }}	hello	string
json	{"y":"world"}	{{ x }}	{"y":"world"}	json
string	{"y":"world"}	{{ x }}	{"y":"world"}	string
number	123	{{ x }}	123	number
string	123	{{ x }}	123	string
empty string		{{ x }}		empty string
string	{{ text }}	{{ x }}	{{ text }}	string
null value	null	{{ x.y }}	null	null value
string	hello	{{ x.y }}	null	null value
json	{"y":"world"}	{{ x.y }}	world	string
empty string		{{ x.y }}	null	empty string
json	{"y":"world"}	{{ x.y }}	world	string
string	{"y":"world"}	{{ x.y }}	null	null value
number	123	{{ x.y }}	null	number
string	123	{{ x.y }}	null	string
json	{"y":123}	{{ x.y }}	123	number
json	{"y":"123"}	{{ x.y }}	123	string
string	{{ text }}	{{ x.y }}	{{ text }}	string

Not replacing sections enclosed in double curly brackets

Use cases require to have a text between curly brackets NOT replaced by the templating engine.

An example body not to be replaced is {{ customer text that should remain in curly brackets }}

In this case, the text not to be replaced can be formatted as follows to maintain the curly brackets

 {{ {{ customer text that should remain in curly brackets }} }}

where the final result would be in the final body (after replacement) is

{{ customer text that should remain in curly brackets }}
