Question

404 reply when recursively listing input items with Responses API

Ola Ingvarsson 25

When listing input items with the Responses API we get the first 20 items. When we try to list the next 20 items using last_id and the after parameter we get an error message like this:

NotFoundError: 404 No item found with id 'msg_681b2a06fbfc8190b8028aa84411af720d7696e647f77df5'

We can see that the message with the above id indeed exists when we list the first 20 items.

Hi @Ola Ingvarsson,

Could you please provide the following additional details so I can assist you more effectively?

Are you using the Azure OpenAI Studio or through an SDK (with complete sample code)?

Which Region and Model are you using?

If possible, please provide a complete screenshot of the error you are encountering?

This will help me pinpoint the issue and suggest a more accurate solution. Thanks!

I'm using the Javascript SDK "openai": "^4.93.0".

Here's the sample code:

const listMessages = async (responseId, lastId = null, messages = []) => {
  const response = await client.responses.inputItems.list(responseId, {
    after: lastId
  });
  
  messages.push(...response.body.data);

  const { has_more, last_id } = response.body;

  if (has_more) {
    return listMessages(responseId, last_id, messages);
  } else {
    return messages;
  }
};

You don't really use a model when listing input items but they were created with GPT-4.1 in region Sweden Central.

Here's the full error message:

Hi Ola Ingvarsson

We checked internally on this case. There seems to be few product group tickets mentioning East US 2 and UK South on Responses API but not Sweden Central

Could you share a full working code hiding Api key and endpoint details. Current shared code is not clear enough to replicate.

Thank you for the collaboration.

Hi,

Here is a complete code example:

const { AzureOpenAI } = require('openai');

const client = new AzureOpenAI({
  apiKey: AZURE_OPENAI_KEY,
  apiVersion: '2025-03-01-preview',
  endpoint: AZURE_OPENAI_ENDPOINT
});

const listMessages = async (responseId, lastId = null, messages = []) => {
  const response = await client.responses.inputItems.list(responseId, {
    after: lastId
  });
  
  messages.push(...response.body.data);

  const { has_more, last_id } = response.body;

  if (has_more) {
    return listMessages(responseId, last_id, messages);
  } else {
    return messages;
  }
};

listMessages(RESPONSE_ID).then(console.log).catch(console.error);

Hello @Ola Ingvarsson ,

We have received an update from our product team regarding the issue. It has been confirmed that there is a backend bug which causes the system to compare message IDs in different formats. Due to this mismatch, the system is unable to locate the correct message and responds with a 404 Not Found error.

At this time, there is no ETA for the resolution of this issue. However, please rest assured that our team is actively monitoring the situation, and we will keep you informed as soon as a fix is implemented.

We appreciate your patience and understanding. Please feel free to reach out if you have any further questions or concerns via comments

Thank you
