Wkflow Error writing to Tableau Hyper output Output Data (211) unable to write compressed

[AlterboyX]

I'm receiving this error when writing to a Tableau hyper file:

Error: Output Data (211): unable to write compressed datablock: cannot flush mapping: FlushViewOfFile(): An unexpected network error occurredContext: 0x5fdfad59.  We've received errors before if the hyper file previously created is still in the output destination folder, and we've changed the existing file's name.  That fix appears to work,  however, we've never received this error before.  I didn't see questions re: this specific 211 error in community, but may have missed it. Any suggestions?  Thanks in advance for your help!

Hi @AlterboyX --

'211' is actually the tool number of your workflow - it doesn't have anything to do with the error!

I have a few questions...Are you writing the .hyper file to a network drive? And have you tried saving your file as a .tde to see if you get the same error?

Ha! Leave it to me to look at the 211 and immediately think 'error'! - Thanks! Yes, it's going to a network drive, and no I haven't tried saving as a .tde to test for same error. Thanks again.

No Problem! There is still an error on that output but searching '211' probably won't help you find how to fix it! (unless someone also magically had that error on tool #211!)

I would try changing your output to a .tde to see if you get the same error first and then I would check to see that there are no issues with connecting to the network drive. I haven't run into this specific error before but a lot of times when I see errors about writing .hyper files, it's one of those 2 things.

If either of these work, make sure you make this as a solution! If not, I would reach out to Alteryx Support at support@alteryx.com

Best,

Much appreciated!  I'll check on those two possibilities and let you know if either solve the issue.

I found it was a network connection error.  Thanks again, Ashley!
