It's very confusing for me to diagnose this problem because the stacktrace gives no information, also there are no additional information in the logs before the exception.

Unfortunately the page is already quite complex, see attached PDF.

Internal note: Above trace happened on metros theme, when using demo theme, still occurs with slightly different trace:
