I'm getting this error when trying to publish my flow in Tableau Server.
I'm getting my data from an Oracle OCI connection (SQL searches), and when I run the flow without the "Tableu Server" tool it goes fine, but when I try to publish it, it breaks with this error. The problem seems to be, as I've found through some tests I made, on the third connection to DB.
I've already tried several things I've found in other posts, such as being sure about the types of my variables (all my strings types are "V_WString", and I've also tryed as "V_String" and the error persists). My databases are not too big and I don't have a memory problem, I'm running it in a SSD.
In some other flows I made, I didn't have any problem in publishing in Tableau Server, but sometimes, such as in this case, this error appears.
I don't know what else I shoud try.
