If you have just run out of light sauce thickener, you can replace it easily and inexpensively.
Make your own substitute for light sauce thickener
Simply use a sealable jar, e.g., an empty jam jar, and fill it with the desired amount of flour and a little water so that you get a thick paste. Shake the mixture vigorously so that as few lumps as possible form. You can now use this flour paste to excellently thicken sauces, soups, stews, etc.
Always use a little at first, adding more gradually so you can see how the consistency changes.
Cornstarch as a sauce thickener
Cornstarch is the main ingredient in sauce thickener, so you can simply use it. For 250 ml of liquid, you need approx. 2 tsp of cornstarch, depending on the desired consistency. You can use corn, potato, or wheat starch here. Furthermore, guar gum, potato flour, and rice flour can also be used as binding agents for sauces. Another option, slightly sweeter, is pudding powder, as it consists mostly of cornstarch.
Breadcrumbs as a sauce thickener
Very simple white or dark breadcrumbs (bought or homemade) can also act as a sauce thickener. Simply stir 1-2 tbsp of breadcrumbs into 250 ml of cooking liquid and let it boil for 2-3 minutes while stirring.
Butter for thickening
Sauces can also be thickened with butter.
Flour lumps in the sauce
If lumps have formed in the sauce, the only thing that helps is careful pureeing with a hand blender. Only mix on the lowest setting here.

Sorry, but that is nonsense. Sauce thickener is based on potato or corn starch, which results in a smooth, "slimy" consistency when thickening. Flour + water results in something more creamy-grainy, which is reminiscent of béchamel sauce. Not necessarily worse, but *definitely* different.
And what, in your opinion, is a good substitute for sauce thickener?
