Getting stuck on my workflow on a format GPT step. Getting a Cannot read property ‘choices’ of undefined error.

const resultsArray = []
for (let result of steps.openai_chat.$return_value) {
  
  // ChatGPT loves to occasionally throw commas after the final element in arrays, so let's remove them
  function removeTrailingCommas(jsonString) {
    const regex = /,\s*(?=])/g;
    return jsonString.replace(regex, '');
  }
  
  // Need some code that will ensure we only get the JSON portion of the response
  // This should be the entire response already, but we can't always trust GPT
  const jsonString = result.data.choices[0].message.content
    .replace(/^[^\{]*?{/, '{')
    .replace(/\}[^}]*?$/,'}')

  const cleanedJsonString = removeTrailingCommas(jsonString)
  
  let jsonObj
  try {
    jsonObj = JSON.parse(cleanedJsonString)
  } catch (error) {
    console.error("Error while parsing cleaned JSON string:")
    console.error(error)
    console.log("Original JSON string:", jsonString)
    console.log(cleanedJsonString)
    console.log("Cleaned JSON string:", cleanedJsonString)
    jsonObj = {}
  }
  
  const response = {
    choice: jsonObj,
    usage: !result.data.usage.total_tokens ? 0 : result.data.usage.total_tokens
  }

resultsArray.push(response)
}

const chatResponse = {

}

console.log(chatResponse.related_topics)

function arraySum (arr) {
  const init = 0
  const sum = arr.reduce((accumulator, currentValue) => accumulator + currentValue, init)
  return sum
}

const finalChatResponse = {
  title: chatResponse.title,
  summary: chatResponse.summary.join(' '),
  sentiment: chatResponse.sentiment,
  main_points: chatResponse.main_points.flat(),
  action_items: chatResponse.action_items.flat(),
  stories: chatResponse.stories.flat(),
  arguments: chatResponse.arguments.flat(),
  follow_up: chatResponse.follow_up.flat(),

related_topics: Array.from(new Set(chatResponse.related_topics.flat().map(item => item.toLowerCase()))).sort(),
tokens: arraySum(chatResponse.usageArray)
}

return finalChatResponse

},
})

Any suggestions would be greatly appreciated.

Thanks,
