Tableau Output Tool - Dates not posting correctly

Question

After Tableau implemented MFA for all services, I transitioned my Publish to Tableau Server tool to the Tableau Output Tool, but I'm having an issue wherein the new tool is not reading dates correctly. I've tried a variety of troubleshooting options with no success. The following error appears every time I attempt to output anything to Tableau with a date format:

Tableau Output (233) Got an invalid value '2020-05-18' for column "Invoicedate", it must be a Date, Timestamp, datetime, or date instance

The field is formatted as date and is reading correctly as date in both Alteryx and Tableau.

Your work around is a good idea.

Curious, are you outputting a .hyper file or .tde file?

Ah unfortunate. I'll proceed for the work around for the time being. Thanks for your help!

I was able to work around the issue by simply publishing my datasource with all date fields as strings and then converting them back to dates within Tableau itself. Unfortunately I've not been able to find any solution that allows me to publish fields formatted as dates using this tool.
