Adwords API V2009 CampaignTargetService SOAP error

[NS]

Hello Everyone,

I am very new to the adwords API and we are using ruby client library.

I updated the gem adword4r to 18.0.0 version yesterday and tried to
update the geotargetting countries in the campaign and I am getting
following SOAP error.

SOAP Error: Unmarshalling Error: Unable to create an instance of
com.google.ads.api.services.campaignmgmt.campaigntarget.v200909.jaxbgen.GeoTarget
(code: 0)

Any help would be highly appreciated.

Thanks,
NS

Hi NS,

This error usually means that you are using the base type GeoTarget
directly in your request. You'll need to use a concrete subtype like
ProximityTarget, etc to avoid this error.

Hi Erik,

Thanks for your reply.

My code doesn't look very different than the example posted at
following URL.

http://code.google.com/p/google-api-adwords-ruby/source/browse/trunk/examples/v200909/set_campaign_targets.rb

As mentioned before, I am very new to this development so please bare
with me here.

Also I have posted my code in another thread at the link below.

Hi NS,

Your code looks correct. Do you have the SOAP XML request and
response that was generated by it?

Hi Erik,

After your yesterday's reply I was trying few things and was checking
my object types and realised that in Ruby arrays are not typed. So I
made following change to the code and it is working fine now.

@campaign_target_srv = @adwords.get_service('CampaignTarget',
latest)

geo_target_list = @campaign_target_srv.module::GeoTargetList.new
geo_target_list.campaignId = @campaign.api_identifier
geo_target_list.targets = []

if @params['geotarget_countries']
@params['geotarget_countries'].each do |country|
geo_target_country =
@campaign_target_srv.module::CountryTarget.new
geo_target_country.excluded = false
geo_target_country.countryCode = country
geo_target_list.targets << geo_target_country
end
end

geo_operation =
@campaign_target_srv.module::CampaignTargetOperation.new
geo_operation.operand = geo_target_list
geo_operation.operator = 'SET'

response = @campaign_target_srv.mutate(geo_operation)

So now I am populating the geo_target_list.targets array directly by
adding CountryTarget object, instead of adding CountryTarget to an
array and assigning an array to gea_target_list.targets.

Hope this helps others.

Thanks,
NS.
