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. [![enter image description here][1]][1] The tables I want to join by the field FUNDO. [![enter image description here][2]][2] Set up for the join.
