Front-end Table Script Error

I have a front-end script that's filtering some JSON objects, displaying only a few key properties, using a map() call. The script works fine, but I'm getting an error every time it executes.

The error is that bg_0.result is undefined

Trevor SullivanOP•17mo ago

But it's not undefined ... it's working properly

Trevor SullivanOP•17mo ago

My items are populated in the result

Trevor SullivanOP•17mo ago

Oh wait ... maybe it's undefined initially, but after bg_0 completes, it calls it again

Could you share a minimal reproduction of your app please

Yup ... this is what was happening. I wrapped the result in an if statement.

if (bg_0.result != undefined) {
  return bg_0.result.map(val => {
    return {
      name: val.name,
      type: val.type,
      status: val.status
    }
  })
}
else {
  return []
}

if (bg_0.result != undefined) {
  return bg_0.result.map(val => {
    return {
      name: val.name,
      type: val.type,
      status: val.status
    }
  })
}
else {
  return []
}

you can also add ? in a few places bg_0.result?.map .... ?? []
