Find Data with Query selection doesn't work

[emmanuel_madarassou1 (emmanuel_madarassou)]

Hi everyone, I’m trying to select cells from a vtu by his name with the Find Data widget. I’m getting this error: Expression '(GeometryNames == " did not produce a valid mask array

Here is my find data input:
")’

What am I doing wrong ?
