Handle undeclared values in Javascript
I'm trying to take the first not null/defined var i.e. (var1 ?? var2 ?? 'no_value). But the issue I'm running into is var2 is defined in a branch that is not always triggered in the workflow so when the coalesce trys to run it fails saying it does not exist. How should I handle this with Buildship.

In BuildShip, when dealing with variables that may not always be defined due to conditional branches, you can utilize the following strategies to handle optional values safely:
1. Default Values: You can define a default value for your variables that might not be initialized in other branches. This way, you ensure that these variables always have a value when you perform null coalescence.
2. Check Existence: Before attempting to use a variable in a coalescing operation, check for its existence using conditional checks. You can create a branch that checks if the variable is set and only then choose to use it, otherwise fallback to a default value.
3. Use Try-Catch Logic: You can build your workflow by adding error-handling logic around the nodes that might not define specific variables. This approach allows you to catch and handle errors gracefully without interrupting the overall flow.
4. Environment Variables: You could use environment constants or settings that define preliminary default values, ensuring there’s always a fallback.
5. Additional Workflow Logic: You can create additional logic to determine whether the variable is defined and then proceed accordingly. This might involve setting an output node or variable to a predetermined value if certain conditions aren't met.
If you need further guidance on implementing a specific solution in BuildShip, you might check out templates or support documents or reach out through in-app support for technical assistance. Alternatively, if you have the exact definition or context of the variables, you could upload it here for more precise advice.
