Polymorphic terminal cannot accept this data type error

[shandy8596]

Hello!

I am trying to connect the TDMS data to the FIFO.read Data after the transpose 2D array function. It gives me an error polymorphic terminal cannot accept this data type. What should I modify? I try to export the data out from the analog input chart. Would it be the correct data?

Does inserting an Always Copy after the transpose fix the issue?  I know years ago there was a bug in LabVIEW that would cause a memory leak but that was in the 2012 time frame, and I see you have this VI saved in 2015.  I opened it in 2020 and if I put an array of double constant, instead of the FIFO Read it wires fine.
