When trying to input a Single Precision float variable into a wildcard pin, a "No matching 'Add' function for 'Float (Single Precision)" error will appear. I was able to work around this by converting the wildcard pin to a Float (double precision). Doing so would allow me to connect the two nodes.
Tested in //UE5/Release-EarlyAccess @ CL 16682836 and this did not occur, so marking as a Regression
The nodes cannot be connected due to a "No matching 'Add' function for 'Float (Single Precision)" error
The pin would convert to a Single Precision Float
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-145388 in the post.
