Hi,

I am getting the following error when I try to download data from DFP API. The issue has started happening from 8-Sep-2016. 

Could you please let me know how to resolve this?

Error:

Hi Subash:

This should be fixed now. Please let me know if you continue to run into this.

Thanks,

Hi Subash:

To help us debug this issue, two questions:

1. What is the email address of the user you used to generate an OAuth2 refresh token with?
2. What OAuth2 scopes are you using?

Thanks,

Hi Vincent,

Thanks for your response. 

The client ID we are using was created with a person's dfp account who has since moved out of our organisation.

So we do not have much information on it. 

But we generated new refresh token for this client ID and secret key. Using this new refresh token we are getting the below error.

Could you please help us resolve this issue. Thanks!

Hi Subash,

I believe there's another thread about this issue that I already replied to, but I'll post here as well. When you generate a refresh token, it's tied to the Google account you are currently logged in to. Based on your description, I suspect the refresh token is tied to an account not in the network.

To handle situations like users leaving the organization, you can share projects on the developer console. If the project owner leaves the organization, you can transfer ownership of the project:

Alternatively, you can use a service account for authentication. The service account flow eliminates refresh tokens and uses a key pair to generate access tokens:

Thanks Chris. 

I will try to get the ownership of the project transferred.

Hi All,

Has this been fixed?  I seem to running into the same error response when I run get_all_line_items.py script from the test examples. I am new to the DFP api and wanted to just try this out on Python before I port it over to my project in .NET.

The YAML file is all set up and I just generated fresh token's this morning in response to this error to check if that was the problem.

Hi All, 

I back tracked through everything and realised that the error was being caused because:

1. I was updating the wrong YAML file........ I didn't realise but the YAML file I had opened was actual the one in the python example folder and not the one I moved to my User folder.

2. After I corrected the YAML issue, I was now getting a '[AuthenticationError.NETWORK_CODE_REQUIRED @ ]' error. So I looked back at the YAML file and realised that the DFP config has the network_code commented out.  Since I hadn't directly set up the DfpClient Object.. So I just commented it, added in the network code and Presto! Data is pulling through!

Silly errors, but hopefully this helps anyone else facing the same issues.

Regards,
