Got below error in our account . URL was index.php?module=CoreHome&action=index&idSite=12&period=week&date=today#?period=week&date=today&category=Dashboard_Dashboard&subcategory=1 but it's a custom dashboard where I have goals in there etc.

Is it the same as #19963?

@tsteur Might be hard to find the reason why a non numeric value occurs for the conversion rate.
We could though change the formatter to check if the given value is numeric and use 0 otherwise maybe.

Thanks. That actually didn't happen when comparing but maybe it's related to the other regressions. It only started with the recent Matomo 4.12 release. We could always see if it still happens after all the other regression fixes and #19970
