[Templating] Complex expressions are not handled properly

Platform

• JavaScript
• .NET

Version of SDK

All versions since release

Details

The templating engine fails to correctly interpret complex expressions such as this one:

"targetElements": "${foreach(foreach(indicesAndValues(LineItems), x, concat('cardContent', x.index)), y, json(concat('{ \"elementId\": \"', y, '\", \"isVisible\": true }')))}"

The reason for this is the code mistakenly interprets the } character after \"isVisible\": true as being the end marker for the expression when it is actually a character within a string within the expression.

@dclaux FYI… You can simplify your expression:

"targetElements": "${foreach(foreach(indicesAndValues(LineItems), x, concat('cardContent', x.index)), y, {elementId: y, isVisible: true})))}"

That’s the same thing as using json() to parse a JSON based string but way easier to write 😃
