Retrying on API/Parse Failures

Wrapping an LLM call and JSON parse in a retry loop that must retry on both errors.

Codejavascript

async function getJson(prompt) {
  for (let i = 0; i < 3; i++) {
    const res = await client.responses.create({ model: "gpt-4o-mini", input: prompt });
    try {
      return JSON.parse(res.output_text);
    } catch (e) {
      return null;
    }
  }
}

What is the bug in this retry logic?
