Crashes when using array of string in "write TDMS"

[krissven]

Hi!

I'm trying to write a variety of data types to a TDMS file. I want the data to be in the same group but different channels. This works fine using numbers, so i can write 2 samples in 7 different channels with unique channel names for instance, as shown in the example here. But if I try to write 2 samples in 2 channels when the data type i sting I get a broken wire. I can't have a string array as data input and a string array as channel names, is this normal ? Furthermore, if I don't input any channel names and just input the array of strings as data (as shown here) Labview crashes. Am I doing something wrong here ?

When I wire a VI the same as you showed in that image then LabVIEW (2021) doesn't crash!

Instead it gives a warning (-2533), but not an error.

Did you read that warning? Did you read the explanation of that warning?

Did you follow the suggestion given in that explanation?

General suggestion: implement error handling in your VI! Then you could easily recognize such errors and warnings!
