CSV Export not working

[proffalken]

Describe the bug

When trying to export the list of members as a CSV file, I get an error in the browser console:

TypeError: Cannot read properties of undefined (reading 'call')
    at es.Q (Members.7f122ddb.js:10:18546)
    at new X (Members.7f122ddb.js:10:40370)

The code appears to be failing on the following block, however as this is generated JS I'm not sure if the line numbers are relevant:

        exportCsv() {
            ts(this.displayMemberList, {
                columns: ["name.full", "email", "state"]
            }, (e,t)=>{
                ui("member-export.csv", t, "text/csv") !== !0 && this.$q.notify({
                    message: this.$t("error.downloadFailed"),
                    color: "negative",
                    icon: "warning"
                })
            }
            )
        },

To Reproduce
