Hi, I'm trying to filter a gallery based on a text entered by a user, the gallery has a connexion to excel online for business conector and the table contains more than 3000 unique values.
I've created a text input named "FilterTextBox" to filter the gallery based on the field "cedula" that has text format in the Tabla1 (the source of the gallery)

This is the formula I'm trying in the Item property of the gallery:
Filter(Tabla1; StartsWith(cedula;FilterTextBox.Text))
It is retrieving "Runtime errors" indicating "the operation required is not valid" as the photo below:

Is there a problem with the conector, the format of the field...? How could I change in my formula to filter by that field?
Thanks in advance,
