reports.compatibleFields - 500 UNKNOWN error?

[Sam Lehman]

Hello,

I've been trying to implement the use of reports.compatableFields (https://developers.google.com/doubleclick-advertisers/rest/v4/reports.compatibleFields/query) to check a profile's report's compatible fields against a provided list of dimensions/metrics.

It works well locally on some users, but I pushed the code changes to staging to test against different customer's credentials and I noticed this call is causing a 500 UNKNOWN error for some reason. Other profile IDs from this same customer are working correctly.

Any Idea what the error might mean?

Example:

Running it on profile ID 5462817,

with report: { "type": "STANDARD" }

and I get the following error:

{"code"=>500, "message"=>"Unknown Error.", "errors"=>[{}], "status"=>"UNKNOWN"}

@phillip, I think it's hitting a rate limit or something, but not returning an error code regarding rate limits. I put a sleep(20) between the two calls I was making and it made the issue subside more or less.

@DCM, I'll respond Monday with that info.

@Sam thanks for coming back. Then we're facing a different issue which have opened a separate thread here https://groups.google.com/g/google-doubleclick-for-advertisers-api/c/5BIHFg9QVFc/m/sW8ewA0XAgAJ
