Did you find a solution for this? Maybe a different version that works?

[suhel-rn]

The issue that I was able to find was that this is not related to the validateJson function, rather it is related to using the gpt-4o model using the free plan of OpenAI.

If you are using the API key from the free plan, clone the repository, and alter the model in the runChatCompletion function to gpt-4o-mini

Something like

const runChatCompletion = async (messages, useGrammar = false, model) => {
  if (model === 'openai') {
    const modelName = 'gpt-4o-mini';
