Handling REST API exceptions

Question

I have an extension that has some code to save a custom object via REST API service.

I have a try and catch (\Exception $e) around the save method, but for some reason I get the following message:

{
    "message":"Internal Error. Details are available in Magento log file. Report ID: webapi-5c481b2831e76"
}

The log shows:

main.CRITICAL: Report ID: webapi-5c481b2831e76; Message: Property "aaa" does not have corresponding setter in class "Company\Module\Api\Data\MyCustomClass"

I assume the error is being thrown from within the REST API code - because the object (which is in the method signature) is not able to be instantiated.

So how to catch this.

Answer 1

The data you sent had to be compatible with the param doc type and probably is a Data Service contract.

If you sent valid data then it will get in the try catch.
