ERROR
Workbooks containing data from an ArcGIS connection using web-tier authentication (IWA, PKI, or LDAP) fail to export.
The failure occurs when the ArcGIS Enterprise setup uses double gated authentication (in other words, web-tier authentication is used on both Portal for ArcGIS and ArcGIS Server. The error will not occur if the setup uses web-tier authentication for Portal for ArcGIS only.
Copy the datasets from the ArcGIS connection to your workbook before exporting the workbook package.
