Trying out the queue system for a better user upload experience with Laravel-Excel.
.env was been changed from 'sync' to 'database' and migrations run. All the necessary use statements are in place yet the error above persists.
The exact error happens here:
Illuminate\Queue\Queue.php:97
$payload = json_encode($this->createPayloadArray($job, $queue, $data));
if (JSON_ERROR_NONE !== json_last_error()) {
throw new InvalidPayloadException(
If I drop ShouldQueue, the file imports perfectly in-session (large file so long wait period for user.)
I've read many stackoverflow, github etc comments on this but I don't have the technical skills to deep-dive to fix my particular situation (most of them speak of UTF-8 but I don't if that's an issue here; I changed the excel save format to UTF-8 but it didn't fix it.)
Ps. Whilst running the migration, I got the error:
SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 767 bytes (SQL: alter table `jobs` add index `jobs_queue_index`(`queue`))
I bypassed by dropping the 'add index'; so my jobs table is not indexed on queue but I don't feel this is the cause.
