TIBCO Spotfire Web Player fails to start after enabling AllowAllFilePaths in service configuration

The TIBCO Spotfire Web Player instance fails to start after adding in the AllowAllFilePaths setting to allow the services access to all files paths for data sources. The following error is seen due to an invalid configuration:

Here is the picture of how it looks through the UI:

                    


  To resolve this issue, ensure to have both the "AllowedFilePaths" and "AllowAllFilePaths" settings in ‘Spotfire.Dxp.Worker.Host.exe.config’ file instead of just AllowAllFilePaths. Otherwise, the TIBCO Spotfire Web Player will not start due to the invalid configuration. 

<setting name="AllowedFilePaths" serializeAs="Xml">
        <value>
          <ArrayOfString>
            <string/>
          </ArrayOfString>
        </value>
      </setting>
  <setting name="AllowAllFilePaths" serializeAs="String">
       <value>True</value>
           </setting>
    </Spotfire.Dxp.Data.Properties.Settings>

If only AllowAllFilePaths is present (AllowedFilePaths was removed when adding AllowAllFilePaths) then you will see the error described in this article. For further instructions on the setting, see the referenced KB article.
