Hello.
I got [AuthorizationError.USER_PERMISSION_DENIED @ ; trigger:'<null>'] when call page = CampaignService.get(selector)
<AdWordsApi>
<add key="UserAgent" value="our product name"/>
<add key="DeveloperToken" value="token (not approved)" />
<add key="ClientCustomerId" value="test account ID"/>
<!-- OAuth2 configuration -->
<add key="OAuth2Mode" value="APPLICATION" />
<add key='AuthorizationMethod' value='OAuth2' />
<add key='OAuth2ClientSecret' value='Client secret from project on PROD account Credential tab' />
<add key='OAuth2RefreshToken' value='Token generated by OAuth2 Token Generator' />
</AdWordsApi>
Test account was added as owner to project on production account. (Permissions-> Add member)
And it's still happen. Could someone help to solve that problem.
Regards Mateusz
