我有一个离子项目正在进行中，我收到了控制台错误

[ng] NOT SUPPORTED: option jsonPointers. Deprecated jsPropertySyntax can be used instead.
[ng] An unhandled exception occurred: Cannot read property 'allErrors' of undefined
[ng] See "/private/var/folders/3f/chjh7cx96mv1zkr690ytb0yr0000gn/T/ng-RX4zto/angular-errors.log" for further details.

angular-errors.log文件如下所示
