GoogleAds beta: Probably incorrect error code when trying to create google app campaign

[Uladzislau Zayats]

Hello.

I was fighting quite a long time with issue in google ads beta api while trying to create google ads campaign. I was not able to create ad for some reason and was getting following error:

GrpcError: Too few.

    at AdGroupAdService.<anonymous> (/usr/src/app/node_modules/google-ads-api/build/services/service.js:200:23)

    at Generator.throw (<anonymous>)

  }

}

Googling about this issue was giving me results about incorrect pinned_field. But in fact - it was not about it. Reason of getting this error was that array of headlines for ad for app campaign was not big enough.

I was trying to create campaign with only 1 headline and getting error above. So after I just added more headlines and was finally able to create campaign ads. Is there any info about minimal amount of headlines in google ads for app campaigns? I did not find it. Here is the link where is no word about minimal amount of headlines: https://developers.google.com/google-ads/api/reference/rpc/v3/AppAdInfo

I would also add that in my opinion error description is not 100% true.

Here is original location in error:

  location: 'operations[0].create.ad.app_ad.headlines.pinned_field',

In my opinion, proper location should be:

  location: 'operations[0].create.ad.app_ad.headlines',

Showing pinned_field in location is confusing as it does not give real reason of failure.

Thanks.
