Bug in CampaignFeedService

[FW API]

Hello, 

we have encountered a probable bug in CampaignFeedService. We have send a request with a CONTAINS_ANY clause according to this documentation:

https://developers.google.com/adwords/api/docs/guides/feed-services-locations#filtering_location_extensions

- The operation apparently worked: The correct four locations are now listed with the campaign. 

- But the soap response contained a FunctionError.INVALID_NUMBER_OF_OPERANDS.

I'll append redacted soap log:

Hi,

Thanks for posting your concern.

Upon checking the provided SOAP logs, I can see that you've set 4 constant operands in the functionString field of matchingFunction. However, according to this documentation, the maximum constant operands that you can set for CONTAINS_ANY operator is three and this is the reason why you encountered the FunctionError.INVALID_NUMBER_OF_OPERANDS.

Let me know if you have further questions.
