Hi,

We’ve been building workflows in n8n for our company and encountered a recurring issue with OAuth2 token refresh. The issue arises when using HTTP tools for AI agents. Although n8n should refresh the token automatically once it expires, we found that after 24 hours, the HTTP tools stop working due to missing credentials. Video and workflow below are examples of a call to HighLevel oAuth2 API.

Interestingly, running a single HTTP request node calling the API seems to refresh the token and restores functionality for all HTTP tools for 24 hours. It took us quite a while to troubleshoot and pinpoint this behavior. Me or Perplexity couldn’t find this being a known issue.

## Video of the issue

## What is the error message (if any)?

There was an error: “Node does not have credential type”

## Please share your workflow

Hi @Tero

Thanks for reporting this! This should be fixed with version `1.65.0`

> <https://github.com/n8n-io/n8n/pull/11343>
>
> \## Summary
> 
> This PR fixes an undefined response from HTTP Tool node in case au…thentication is enabled.
> 
> Since this PR was merged (https://github.com/n8n-io/n8n/pull/11219) HTTP tool node requires a full response. But the underlying implementation for the request may differ, depending on authentication setting, and so the name of the option to get the full response.
> 
> HTTP Tool Node now uses \`helpers.httpRequestWithAuthentication\` instead of deprecated \`helpers.requestWithAuthentication\`, so now it should respect the \`returnFullResponse\` option.
