GraphQLControllerBase::extract_previous_chain │ private │ WC 1.0

Walk the getPrevious() chain of a Throwable and return one entry per wrapped exception. Used in debug mode so that resolver-level wrappers (which bury the real cause behind a generic "INTERNAL_ERROR") still surface the underlying class/message/file/line/trace.

Method of the class: GraphQLControllerBase{}

No Hooks.

Returns

Array. array{class: string, message: string, file: string, line: int, trace: string[]}>

Usage

// private - for code of main (parent) class only
$result = $this->extract_previous_chain( $e ): array;
$e(Throwable) (required)
The outermost exception.
