Error Connecting Terminals of Different Types Through For or While Loops

Issue Details

• I wired an error wire through a loop and it gave an error for connecting two terminals of different types. The  error says that the type of the source is a 1D array of cluster of 3 elements. The type of the sink is cluster of 3 elements.
• I am using a loop and my data is being collected correctly inside of the loop, but when I try to process or log the data after the loop, I receive a type mismatch error similar to the one above. Why is my data being rejected?

Solution

Additional Information

• The auto-indexing tunnel mode builds an array of the values from all iterations of the loop. This will cause an error when the sinking terminal expects values that are not arrays.
• Auto-indexing tunnels can be helpful as a replacement for collecting data in a shift register and adding new data to that shift register during each loop iteration. However, be careful that your code does not include both a shift register-based and auto-indexing-based implementation for collecting multiple iterations of data. It is likely that only one is needed.
• In similar cases, this issue can sometimes be quickly resolved by concatenating all members of the array into a single data structure. This can be helpful when working with waveforms that should contain merged data in a single waveform, rather than an array of waveforms.
