Amazon Ads API: TypeError

Hi there,

sorry if this is a newbie questions.

I’ve followed the Amazon Ads API instruction and I’m stuck at this step here.

Meaning I’ve successfully generated a report via postman (status 200 ok).

But when trying to request the status, I get the following error:

There was an error in evaluating the Pre-request Script:TypeError: Cannot read properties of undefined (reading ‘startsWith’)

Does anyone know why this happens and how to solve this?

Thanks so much :slight_smile: !

The error is being caused by code in a pre-request script, so logically that is where you need to start. You can have pre-request scripts on the request, folder or collection, so you might need to check all of those locations.

Hi Mike,

thanks for your quick reply, I appreciate it :slight_smile: !

I did find a pre-request script, see the attached screenshot.

However, this is the original code provided by Amazon.

All I did is follow their developer instructions and installed the environment and collection files.

So it works out of the box, and I didn’t change anything, especially not the scripts.

Are you saying I need to meddle with the original Amazon code?

I would assume they know what they were doing and the code is fine as is?

Thanks!
