UNEXPECTED_INTERNAL_API_ERROR AdGroupAdService

[Luigi Taccetta]

I have a process which is fetching the Ads for several users, the following API call is done several times a day, just with different Google Tokens.

Sometimes, and I don't know why, I get the InternalApiError.UNEXPECTED_INTERNAL_API_ERROR

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    <soap:Body>
        <soap:Fault>
            <faultcode>soap:Server</faultcode>

            <detail>
                <ApiExceptionFault xmlns="https://adwords.google.com/api/adwords/cm/v201802">
                    <message>InternalApiError.UNEXPECTED_INTERNAL_API_ERROR @ com.google.ads.api.services.common.error.InternalApiError.&lt;init&gt;(InternalApiErro</message>
                    <ApplicationException.Type>ApiException</ApplicationException.Type>
                    <errors xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="InternalApiError">

                        <ApiError.Type>InternalApiError</ApiError.Type>
                        <reason>UNEXPECTED_INTERNAL_API_ERROR</reason>
                    </errors>
                </ApiExceptionFault>
            </detail>
        </soap:Fault>
    </soap:Body>
</soap:Envelope>

Is there something I can do to avoid it?
Which one is the best way to deal with it, just retrying?

Is there a way to get a more specific error message?

Hello Luigi,

Could you confirm how often you are seeing these errors and from when you are facing this issue? Could you please share the SOAP logs without redacting any information so that we can take a closed look? you could use reply privately to the author option while share the details requested.
