Hyper File Extension Error When Trying to Output to Tableau TDE

[hellyars]

I keep getting this error when trying to output to a .TDE fle

Error: Output Data (39): Hyper files must use the file extension `.hyper`
Context: 0x5fdfad59
File_Output: Output Data (39): D:\.......\alpha.tde"

What the freak?  Three years, never seen this (and of course) I am working all weekend.

Hi @hellyars — Notice the error msg... must use *.hyper file-format.

hope this could give you some idea:

Extract Upgrade to .hyper Format

I still do not know what happened.  Support suggested it might be a Windows, Anti-Virus, Alteryx thing and said best to reinstall my OS (vs. gather logs and wait, I had a deadline).  So, I restored my PC from a mirror.  

But, the problem persisted on the new machine.  Problem never occurred until I used 2021.2.  So, I did some testing.  A sample workflow could thrown into 2020.3 had no issues outputting to TDE.  The sample workflow had no problem doing it 2021.2.   So, I turned my attention to the original workflow that generated the error.  I deleted all the macros and tools between the input and output; it failed. So, I just replaced the Output Tool and it worked. 

Correlation does not equal causation, but I have to think its workflow related.  But, I can't rule out the anti-virus as the culprit for its corruption.  Malwarebytes updated Friday.  Malwarebytes started going after Alateryx when I fired it up Saturday.  And, it was not until mid-day that I tried to export to TDE.  And if I recall correctly, this workflow failed Friday (while others did not) with a big red "X" across the canvas.
