Hi, I have a FPGA_main.vi that connect a FIFO (called V_out) to two AO channels. And in the main.vi, I combine two "constant" through "build array" to "invoke method - write" to the FIFO.
However there is a broken wire that says I'm connecting double to "sink 1-D array of void".
I've seen examples of both using "build array" and "join numbers" to send data to "invoke method write", but I guess my problem is to do with the "1D array of void".
The FIFO is also defined in project, and is Host to Target. Can someone tell me what I'm missing?

Update: problem solved.
Basically I just deleted the invoke method, and added back to it. I think the issue is that even though I referenced FPGA file after creating invoke method, the invoke method is not updated. I needed to add invoke method block after referencing. Basically, invoke method does not automatically updates itself that FPGA is referenced.
