Multi-part Queries are Disabled

[Goran]

Hi everyone,

For the last couple of days I've been getting an odd error I haven't seen before.  I have a flow which combines a number of Alteryx databases into a single Tableau hyper file.  I then have another flow which combines 4 of these Tableau hyper files into a single hyper file along with a few other processes.

For some reason, when ever I input this one hyper file into the 2nd flow I always get the follow error message: Multipart queries are disabled.  I have had this flow for a few months and only the last couple of days has this error came up.  It only comes up in one hyper file. 

Does anyone know what this error means or what its referring to?  If so, any ideas how to get around it?  

Thanks!!
