Custom Actions ignore properties having value "false" in outputs

[fvoron]

Hey there!

I was implementing an API call thanks to Custom Actions and came across this : if there is a boolean property with the value false in the API output, it’s not shown in the outputs properties. Boolean properties with value true do are shown.

I’ve setup a dummy API to reproduce it : https://5fc616164931580016e3c972.mockapi.io/dummy/1

{
  "id": "1",
  "true_property": true,
  "false_property": false,
  "null_property": null
}

where true_property is always true, false_property is always false and null_property is always null.

Steps to reproduce

• Add a button component
• Add a new Custom Action on it
• Name it “Test” with type “Create” (doesn’t matter)
• URL : https://5fc616164931580016e3c972.mockapi.io/dummy/1
• Method : GET
• Run test request

Actual behaviour

• The property false_property is not shown in the outputs
• If you look at the full response, the property is there

Expected behaviour

• The property false_property should be in the outputs

Remarks

We see that null values are also ignored. In my opinion, it looks like a typical problem of truthiness check in the implementation:

if (output[property]) {
  ...
}

instead of

if (output[property] !== null) {
  ...
}

Could you look into it? Would be happy to help if needed.

Best regards!

Thanks for a detailed submission. I will reproduce it on my end then forward it on to the team!
