How to use the cwlts/models/helpers/validation.ErrorCode.EXPR_ALL function in cwlts

this.modal.delete("Base Command").then(() => {

            // Reset the expression's validity
            // @TODO: if this is an ExpressionModel, model won't revalidate when an entry is removed
            const entryAtIndex = this.formControl.at(index).value;

            if (entryAtIndex instanceof ExpressionModel) {
                entryAtIndex.clearIssue(ErrorCode.EXPR_ALL);
            }

            this.formControl.removeAt(index);
            this.cdr.markForCheck();
        }, err => {
            console.warn(err);

this.modal.delete("secondary file").then(() => {
            // Reset the expression's validity
            const entryAtIndex = this.formControl.at(index).value;

            if (entryAtIndex) {
                entryAtIndex.clearIssue(ErrorCode.EXPR_ALL);
            }

            this.formControl.removeAt(index);
            this.cdr.markForCheck();
        }, err => {
            console.warn(err);

this.modal.delete("hint").then(() => {
            this.model.hints[i].clearIssue(ErrorCode.EXPR_ALL);
            this.model.hints.splice(i, 1);
            (this.form.get("hints") as FormArray).removeAt(i);
            this.update.emit(this.model.hints);
        }, err => {
            console.warn(err);
