How to set custom handler arguments via Application settings?

[xlight05]

Question

I'm in the process of adding debugging capabilities for Ballerina Azure functions ;). Ballerina is implemented using Custom handlers. I need to pass debug args to start the ballerina debug server upon func start. I noticed, in other languages such as java you can use the field "languageWorkers__java__arguments" in application settings to do this. What is the equivalent of that for custom handlers?

Please note I want to do this using application settings. not host.json as we need vscode impl, we need to programmatically set these.

What language does your question apply to? (e.g. C#, JavaScript, Java, All)

Here is the documentation for setting arguments for custom handlers.

Here is the documentation that describes how to override host.json config using app settings.

Mainly you need to use the app setting in the following format. AzureFunctionsJobHost__path__to__setting in your case it should translate to AzureFunctionsJobHost__customHandler__arguments
