I was making a mistake in creating a PLA single product ad.
At the same time, I found that in addition to the above api, AdGroupCriterionService also has problems. And I'm sure all my API operations are single-threaded. And not operating on ad WEB

This problem also existed before, but the frequency is not large. But the probability of recent occurrence is great. Looking forward to your good news

Hi,

The issue on this thread should already be fixed. You may try to do your request again and confirm. If the error still persist, kindly provide the new generated complete SOAP request and response logs so I could investigate on this. You may use the reply privately to author option.
