Where to find relevant log file for REST API?

[hauscloudmf3d0]

Hi Community Members,

I'm using a swagger generated api and trying to create a shipment for an order. I'm using this endpoint from the api reference click me . I get the error {"message":"Could not save a shipment, see error log for details"} and can't find the log file for debug information. Any help would be much appreciated.

side questions:

Why do some api responses possess "web-api <reference_id>"  and others do not?

Hello @hauscloudmf3d0 ,

Execute the following command from your Magento root directory(suppose your reference id is 123456789 i.e webapi-123456789)

grep -r "webapi-123456789" var/

 This will show the name of the log file. Hopefully, it is in exception.log, open the log file, and search for webapi-123456789 you will get detailed about your error in detail.

If this helps you, please accept this as a solution and give kudos.

@Nishu Jindal How does developer mode and logging mode fit in? Does developer mode and/or logging have to be turned on? I was just wondering after reading the articles below.
