Not allowed to add image extension

[Peter Baptist]

I have uploaded the image asset using the following Java code: https://github.com/googleads/google-ads-java/blob/64edbf9a03373e9fa8142caa59a8ab4705aa0086/google-ads-examples/src/main/java/com/google/ads/googleads/examples/misc/UploadImageAsset.java

And it is working fine, but I do not receive permission when I try do add the image asset  obtained early as a image extension using this code: https://github.com/googleads/google-ads-java/blob/64edbf9a03373e9fa8142caa59a8ab4705aa0086/google-ads-examples/src/main/java/com/google/ads/googleads/examples/extensions/AddImageExtension.java

I have done many operations using basic and advanced example codes and they work like a charm. I am using a test account.

Check the result:
