The second argument of the lv_obj_set_style_bg_img_src function is the TemporaryImage variable, which does not contain the name of the actual image file’s table name.
I am looking for the table name of the corresponding image from the .c file under images and replacing it with ui_img_xxxxx, but I would like it to be supported when generated.
This bug did not occur as long as the component was created in a new project using the latest version of the tool.
It seems to be a bug that occurs when exporting a component of a project created before SLS 1.3.0 with a newer version.
So it looks good. Probably the it fixed itself as we have imported the project. As workaround, I think editing and saving the component will fix it as well. Could you try it out?
