Problem:

'Export Image' failed with: System.UnauthorizedAccessException: Access to the path '\\Servername\SampleFolder\Sampleimage.png' is denied in TIBCO Spotfire Automation Services

Solution:

TIBCO Spotfire Automation Services task to export images or data to external file fail with the error - 'Export Image' failed with: System.UnauthorizedAccessException: Access to the path '\\Servername\SampleFolder\Sampleimage.png' is denied.

Cause:

1). File path is not defined under AllowFilepath configuration.

2). The Node Manager Service Account does not have appropriate permission to the folder.
> Confirm that the Node Manager service account has read access to the Shared drive.

> By default allowedFilePaths allowAll value is set to "True" , but if you see the above error then the value maybe set to "False.
Below are the steps to update the configuration:

Follow the instructions from the below KB article to export the existing or old configuration

https://support.tibco.com/s/article/How-to-export-a-previous-old-service-configuration-for-the-Web-Player-or-Automation-Services-or-TERR-Services

Update the Spotfire.Dxp.Worker.Automation.config exported at <Spotfire Server Install>\tomcat\bin\config folder(for version 10.2 and lower) and <Spotfire Server Install>\tomcat\spotfire-bin\config (for 10.3 and higher)
If you want to be able to export to any folder then the allowAll attribute should be set to "True" e.g. <allowedFilePaths allowAll="True">
Or add path in the below section with the path you would want to all the automation service job to export

===================

<allowedFilePaths allowAll="false">
     <add path=".\Temp\" />
     <add path="C:\Temp\" />
     <add path="\\MyServer\Spotfire Exported PDF\" />
</allowedFilePaths>
====================

Save the config file and import it as follows.

config import-service-config --config-name="AllowExportpath"

Provide the config Tool Password when prompted.
Login to the Spotfire Admin console > Open "Nodes and Services".
Click on Automation Service > Click "Edit"on the right hand top corner.
Select the new configuration and update.
