Module Output not reading model data

Hi @W_Seggos !

Although I couldn't find anything mentioned in the Retool docs on Module outputs that it requires Values to be strings, from my recent experience working with Retool Module outputs and looking at the Error message in your screenshot, I believe this is because what you're supplying as a Value (i.e. Map.model.areaSqFt) is not a string.

What I'm doing to work around this is:

• use JSON.stringify() to stringify the value I want to use as Module output
• use JSON.parse() in the app where I consume the Module output

So in your case, I would put {{ JSON.stringify(Map.model.areaSqFt) }} in the Value for outputAreaSqFt. Then when I want to use the module output in an app, I would do:
{{ JSON.parse(module.outputAreaSqFt) }} to get it back to it's original type.

Here's an example app and module:
Example Module with Output using JSON.stringify.json (9.0 KB)

Example App Using Module with Stringified Output.json (12.9 KB)

Hope this helps!
