Contribution Aggregate by Relationship civireport has deprecation notice about formatting non-numeric values
User deprecated function: Formatting non-numeric values is no longer supported: Díaz, Santina Caller: CRM_Utils_Money::formatLocaleNumericRoundedByPrecision in CRM_Core_Error::deprecatedWarning() (line 1060 of /srv/buildkit/build/dmaster/web/sites/all/modules/civicrm/CRM/Core/Error.php).
Repeated many times.
A proper solution maybe involves checking the field data type first but a quick fix is to wrap https://github.com/civicrm/civicrm-core/blob/28878097fa2908956cac2df1f63e7ce32bb85668/CRM/Report/Form/Contribute/History.php#L821 with if is_numeric($value) {
:
L821: $value = CRM_Utils_Money::formatLocaleNumericRoundedForDefaultCurrency($value);
The reason that quickfix isn't enough is because this report will do something like format a postal code 90210 as "90,210.00" if you include that field in the columns, but that pre-dates the deprecation.
