hello guys, does anyone also can't insert the variables on the nodes? every time I create a node I can't insert a variable, even if I create it. The variable just doesn't save no matter how many times I try it, and then the tool to capture information keeps in red. what do I do? I do not speak english very well and I could not find a solution

you could refer to this maybe?
