I've checked my AWS credentials and there is no issue, does anyone have any suggestions?

Describe the problem/error/question

I’m currently POST requesting a set of messages to AWS lambda, however, it keeps saying there’s an issue with the credentials, however I’ve checked the connection with my credentials and its okay.

What is the error message (if any)?

ERROR: Forbidden - perhaps check your credentials?
{“message”: “Missing Authentication Token”}

Hi @Jamaal :wave: I just tried testing with AWS Lambda there and had no issues invoking a function with my credentials - can you double check that you’ve selected the correct region when you’ve created your credentials?

Thanks for getting back to me, I’ve realised I was sending it to the wrong API, as you can see below, this is the API I’m meant to send it to, however, I’m still coming across an issue as you can see below

The image above is the Headers that are assigned to the HTTP link

Above is the Information I’ve sent from bubble to n8n, when I do my content-type as application/json, I don’t come across any issues with initialising my API however when I use plain/text there is an issue with initialising my API, however, it still sends the information, do you have any suggestions on what I should change?

Without the URL or the specific API I can’t be sure - but as a first step I’d recommend upgrading to 1.8.2, then removing the HTTP Request node and adding a new one from scratch (to make sure you’re using the latest version of the node).

if that doesn’t work, can you share which API and the exact error when setting the content-type header to text/plain?

My Json code was the issue, thanks for your help
