Union function missing from function list

I would like to use the union function to get a unique value array from my input array. I have seen many posts that discuss how to use this function to achieve this. However when i have tried to do this I have found that the union function is not in the function list. Am I using the wrong card or is this function only for certain connectors? This is a screen shot of my flow and the error when trying to find union in the functions list.This is a screen shot of my flow and the error when trying to find union in the functions list.

Hi @Sitaneph :

I reproduced this problem, the reason for the error is that you did not enter the complete formula:

vbofengmsft_0-1626658385390.png

The complete formula should be something like this:

union('<collection1>', '<collection2>', ...)

Some thing like :

In addition, even if there is no related function in the recommended function list, as long as the formula you enter is okay, then it should still work.

Best Regards,

Yes just typing in the full expression with correct parameters worked. It is useful to know that this is the case.
