I have the following code and don’t understand why the error occurs.

let kwText = "* " + this.wochenziel + " *";
        kwSlot
            .text(kwText)
            .css("white-space", "nowrap")
            .css("position", "relative")
            .css("float", "left")
            .appendTo(`.wochenziel[data-kwindex="0"`);

I can narrow down when the error occurs. Whenever there is a special character like

. ,

or

!

etc. at the end of the sentence, I get the error. Without a punctuation mark at the end, I don’t get the error.

The data comes from the database.

replace .text to .innerHTML
change the Variable Type
