Message U_PATTERN_SYNTAX_ERROR - What is it?

Hello Erik,

Since yesterday, for some reason I cannot find, I have this message generated by a blueprint containing a spline:

I am parsing the whole BP with care but I don’t see anything special and it seems to work normally. Yet everytime I change a parameter on this BP in the editor I get this error message displayed on the screen.

Do you have any idea about what it could be?

Thank you very much,


Ok, problem solved.
Pfff, not easy to track.
So it was due to a bad syntax in a Format Text node. My bad.

It would be very nice, if not helpful, to have a reference of the node or its class also displayed with this message when such a case occurs.
