HandleKeywordPolicyViolations not getting the right exception

[SeriousJ55]

The code in examples/ErrorHandling/HandleKeywordPolicyViolations.php doesn't work because policy violations of a keyword are thrown as ApiExceptions and not as GoogleAdsExceptions.

For instance, here are the first lines an error received for a policy violation:

object(Google\ApiCore\ApiException)#28230 (11) { ["message":protected]=> string(3883) "{ "message": "Request contains an invalid argument.", "code": 3, "status": "INVALID_ARGUMENT", "details": [ { "@type": "type.googleapis.com/google.ads.googleads.v15.errors.GoogleAdsFailure", "errors": [ { "errorCode": { "policyViolationError": "POLICY_ERROR" }, "message": "A policy was violated. See PolicyViolationDetails for more detail.", "trigger": { "stringValue": "Atestado para Comprovar Rela\u00e7\u00e3o de Prestador de Servi\u00e7os" }, "location": { "fieldPathElements": [ { "fieldName": "operations", "index": 0 }, { "fieldName": "create" }, { "fieldName": "keyword" }, { "fieldName": "text" } ] }, "details": { "policyViolationDetails": { "externalPolicyDescription": [...]

As you can see, this is an ApiException. So I can't access the associated policyViolationDetailsKey and thus can't ask for an exemption.

What am I missing?
