This is a limitation in Lightning and mobile app.

addError(errorMsg, escape)

Marks a trigger record with a custom error message, specifies if the error message should be escaped, and prevents any DML operation from occurring.

Parameters

  1. errorMsg :- Type: String The error message to mark the record with.
  2. escape:-Type: Boolean Indicates whether any HTML markup in the custom error message should be escaped (true) or not (false). This parameter is ignored in Lightning Experience and the Salesforce app and the HTML is always escaped. The escape parameter only applies in Salesforce Classic.

Usage

The escaped characters are: \n, <, >, &, ", \, \u2028, \u2029, and \u00a9. As a result, HTML markup is not rendered; instead, it is displayed as text in the Salesforce user interface.

Warning

Be cautious if you specify false for the escape argument. Unescaped strings displayed in the Salesforce user interface can represent a vulnerability in the system because these strings might contain harmful code. If you want to include HTML markup in the error message, call this method with a false escape argument. Make sure that you escape any dynamic content, such as input field values. Otherwise, specify true for the escape argument or call addError(String errorMsg) instead.
