Help to deal with a error AuthenticationError.OAUTH_TOKEN_INVALID
I do inquiry by an example https://developers.google.com/adwords/api/docs/guides/reporting

__rdxml="<reportDefinition>
      <id>1111111111</id>
        <selector>
          <fields>CampaignId</fields>
          <fields>Id</fields>
          <fields>Impressions</fields>
          <fields>Clicks</fields>
          <fields>Cost</fields>
          <predicates>
            <field>Status</field>
            <operator>IN</operator>
            <values>ENABLED</values>
            <values>PAUSED</values>
          </predicates>
        </selector>
        <reportName>Custom Adgroup Performance Report</reportName>
        <reportType>ADGROUP_PERFORMANCE_REPORT</reportType>
        <dateRangeType>LAST_7_DAYS</dateRangeType>

Authorization =  "Bearer ya29.rgB3ZcocK-pwC7ksEClk9SU3W428m_Kw3BHwE7JJyN-sAKx84FUfO8gEh5"

developerToken =  "XХХХ-ХХХХХХХХХ_ХХХХХХ"

clientCustomerId = "111-111-1111"
