java.lang.NullPointerException after trying to get traffic estimations

[Jorge Brasil]

Hi, 

After following all the instructions and spending a lot of time reading this forum I'm still getting that message when trying to get traffic estimations.

I had an application running on V201404 which has been discontinued so I start my migration process. After running into to several issues I've decide to use adwords examples to figure out what was going on.

I've followed every step that is on your git hub rep, download Jar import the project and then start to use it.

what is strange is that some of the examples run without issues but the traffic estimations don't, not for v201406 or for v201409 so I think that I can assume that my credentials file is ok.

I didn't make any changes, I'm using everything as it is is the website but that error message keeps poping everytime that I try and get traffic estimations.

I really need some help and I've tried everything, even making the requests using python(the outcome was the same null).

Thanks in advance

Hi Jorge,

If you can capture a SOAP request and response XML and post it after removing the credentials and developerToken from the request XML, it would be most useful. See https://github.com/googleads/googleads-java-lib#how-do-i-enable-logging for details on how to capture SOAP logs using Java library.

Hi Anash,

I can't find that file and I think I know why.

Those xml are going to be created with the lo4j login right?

And I'm receiving this message 

log4j:WARN No appenders could be found for logger (org.apache.commons.configuration.PropertiesConfiguration).

log4j:WARN Please initialize the log4j system properly.

log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

Exception in thread "main" java.lang.NullPointerException

at adwords.axis.v201409.optimization.EstimateKeywordTraffic.runExample(EstimateKeywordTraffic.java:144)

at adwords.axis.v201409.optimization.EstimateKeywordTraffic.main(EstimateKeywordTraffic.java:70)

this is my full error message.

Maybe the reason that I am receiving Null response from the API is due to the log4j malfunction on my machine, no?

Is there any chance that you can help me? I don't really know what to do anymore.

Hi Jorge,

Could you send the following only to me by clicking Reply to Author?

• The date and time (including timezone) of one of your failed requests
• The clientCustomerId you are using
• The developerToken you are using

The log4j messages are just warnings -- they won't cause the failures you are seeing.

Thanks,
