I have a shape file with polygons and a xlsx sheet, and I need to join their tables using Join attributes by field value in the modeler.

At QGIS 2.18 it works perfectly, but in 3.4.7 the join doesn't work, but if I do a manual join at the properties of the shape, the join happens normally.

I´m looking for some help with this tool to use **in the modeler**.

Both colums have the same type and size. I already tried to reinstall QGIS and tried on different machines.

Here are some prints to shows the issue.
