How to escape double quote

BPMN & Modeling Discussion & Questions
1

I’m trying to put a string contains a double quote in the output (default output expression language is FEEL), and I tried to use \ to escape the "
For example:

<outputEntry id="LiteralExpression_0kvuate">
      <text>"\""</text>
</outputEntry>

However, I got exception when evaluating the decision.

Caused by: org.camunda.bpm.dmn.feel.impl.FeelException: FEEL/SCALA-01008 Error while evaluating expression: failed to parse expression '"\""': [1.4] failure: end of input expected

Which version do you use?

Please try with the latest 7.16 release.

can you kindly specify which syntax to use? Also, is Camunda DMN-Simulator using the latest version?

Please have a look at the docs: Data Types | FEEL-Scala
