Dear Google Ads API Forum,

I have a repeating issue when invoke Google Ads API, in general it works well, but it happens pretty often that processing of campaigns, groups or keywords using API interrupts with the exception:

com.google.api.ads.adwords.axis.v201809.cm.ApiException: null at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:423) at java.lang.Class.newInstance(Class.java:442) at org.apache.axis.encoding.ser.BeanDeserializer.<init>(BeanDeserializer.java:104) at org.apache.axis.encoding.ser.BeanDeserializer.<init>(BeanDeserializer.java:90) at com.google.api.ads.adwords.axis.v201809.cm.ApiException.getDeserializer(ApiException.java:165) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.apache.axis.encoding.ser.BaseDeserializerFactory.getSpecialized(BaseDeserializerFactory.java:154) at org.apache.axis.encoding.ser.BaseDeserializerFactory.getDeserializerAs(BaseDeserializerFactory.java:84) at org.apache.axis.encoding.DeserializationContext.getDeserializer(DeserializationContext.java:464) at org.apache.axis.encoding.DeserializationContext.getDeserializerForType(DeserializationContext.java:547) at org.apache.axis.message.SOAPFaultDetailsBuilder.onStartChild(SOAPFaultDetailsBuilder.java:157) at org.apache.axis.encoding.DeserializationContext.startElement(DeserializationContext.java:1035) at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.startElement(AbstractSAXParser.java:509) at com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl.scanStartElement(XMLNSDocumentScannerImpl.java:374) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl$FragmentContentDriver.next(XMLDocumentFragmentScannerImpl.java:2784) at com.sun.org.apache.xerces.internal.impl.XMLDocumentScannerImpl.next(XMLDocumentScannerImpl.java:602) at com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl.next(XMLNSDocumentScannerImpl.java:112) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanDocument(XMLDocumentFragmentScannerImpl.java:505) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:842) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:771) at com.sun.org.apache.xerces.internal.parsers.XMLParser.parse(XMLParser.java:141) at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.parse(AbstractSAXParser.java:1213) at com.sun.org.apache.xerces.internal.jaxp.SAXParserImpl$JAXPSAXParser.parse(SAXParserImpl.java:643) at com.sun.org.apache.xerces.internal.jaxp.SAXParserImpl.parse(SAXParserImpl.java:327) at org.apache.axis.encoding.DeserializationContext.parse(DeserializationContext.java:227) at org.apache.axis.SOAPPart.getAsSOAPEnvelope(SOAPPart.java:696) at org.apache.axis.Message.getSOAPEnvelope(Message.java:435) at org.apache.axis.handlers.soap.MustUnderstandChecker.invoke(MustUnderstandChecker.java:62) at org.apache.axis.client.AxisClient.invoke(AxisClient.java:206) at org.apache.axis.client.Call.invokeEngine(Call.java:2784) at org.apache.axis.client.Call.invoke(Call.java:2767) at org.apache.axis.client.Call.invoke(Call.java:2443) at org.apache.axis.client.Call.invoke(Call.java:2366) at org.apache.axis.client.Call.invoke(Call.java:1812) at com.google.api.ads.adwords.axis.v201809.cm.CampaignServiceSoapBindingStub.get(CampaignServiceSoapBindingStub.java:1560) at sun.reflect.GeneratedMethodAccessor386.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at com.google.api.ads.common.lib.soap.SoapClientHandler.invoke(SoapClientHandler.java:100) at com.google.api.ads.common.lib.soap.axis.AxisHandler.invokeSoapCall(AxisHandler.java:234) at com.google.api.ads.common.lib.soap.SoapServiceClient.callSoapClient(SoapServiceClient.java:63) at com.google.api.ads.common.lib.soap.SoapServiceClient.invoke(SoapServiceClient.java:93) at com.sun.proxy.$Proxy206.get(Unknown Source).......

Code fragments where the exception happens are the following:

1) List<AdGroupCriterionOperation> someOperations = ....

AdGroupCriterionOperation[] operations =

        someOperations.toArray(new AdGroupCriterionOperation[someOperations.size()]);
   AdGroupCriterionReturnValue result = adGroupCriterionService.mutate(operations);

2) SelectorBuilder builder = new SelectorBuilder();

Selector selector = builder
        .fields(CampaignField.Id, CampaignField.Name, CampaignField.Status)
        .equals(CampaignField.Id, googleCampaignId)
        .limit(1)
        .build();

// Get all campaigns.
CampaignPage page = campaignService.get(selector);

Could you please advise something related to this issue? Need your help very much.

Best regards and thank you in advance,

Daria
