Laravel job batch: PendingDispatch::__invoke() does not exist

When processing a job batch, when it goes to the next job and finishes it is throwing a reflection exception. You can find my exception details on Flare.

I’ve seen other posts about Reflection exceptions, so I’ve tried

• Restarting valet
• composer update
• composer dump-autoload

My job is dispatched using the following code:

$batch = Bus::batch(
    $this->sisProvider()
        ->syncSchools()
        ->filter(fn (School $school) => $school->active)
        ->map(fn (School $school) => SyncSchool::dispatch($school))
)->then(function (Batch $batch) {
    $this->notifySyncEmails(TenantSyncComplete::class);
})->catch(function (Batch $batch, Throwable $ex) {
    $this->notifySyncEmails(TenantSyncFailed::class);
})->finally(function (Batch $batch) {
    $this->update(['batch_id' => null]);
})->name('Tenant SIS Sync')->dispatch();

Method 1

The problem was how the batch was built. Calling SyncSchool::dispatch($school) dispatches that job independently and returns a PendingDispatch. So a PendingDispatch was put in the batch, not my desired SyncSchool job.

Changing SyncSchool::dispatch($school) in my map to new SyncSchool($school) correctly puts the SyncSchool job in the batch.

Lesson: read the docs closely.
