Resolution
Tableau Desktop Publishing
1. When Tableau Desktop connects to the source, the file path should be the exact UNC path.


2. When publishing to Tableau Server, uncheck the box Include external files.
Tableau Server Updates
On the Tableau Server machine, add the UNC path in the allowlist as per this article: Configure a server allowlist for file-based data sources. See Part 11:Configure a server allowlist for file-based data sources. The example details are as follows:
- tsm configuration set -k native_api.allowed_paths -v "\\dvfilesrvxxxx\bxxxxx\cxxxx\_Gxxxx\0xxxxx\094xxxxx"
- tsm pending-changes apply
If using a Prep flow, then review the article: Step 4: Safe list Input and Output locations. The example details are as follows:
tsm configuration set -k maestro.input.allowed_paths -v your_networkdirectory_path_1;your_networkdirectory_path_2
tsm pending-changes apply
tsm configuration set -k maestro.output.allowed_paths -v your_networkdirectory_path_1;your_networkdirectory_path_2
tsm pending-changes apply
