Scheduled events returning errors

Hello Denis!

I am really sorry to hear about this experience with our plugin! I would have a few questions for you, just to create some context around this:

1. Is this a new plugin installation when you have noticed this? Or have you noticed this after a plugin update?

2. Can you also confirm which plugin version are you using (latest is 5.2.1) ? Also, are you using the Free or Premium edition when noticing this?

3. Can you also describe a bit when this error gets generated? Are there any particular steps to reproduce this? Have you noticed the error only once, or did you notice it being generated constantly?

4. Have you noticed any (bad) effects coming from the error on your site or plugin functionality?

5. Does your website use WordPress Cron (WP Cron) or a server-side cron alternative?

Looking forward to hearing back from you on this.

We are getting the same issue on 5.2.1 Free version. This cron seems to constantly run when this happens recreating a recurring task over and over within the Activity Log. Any ideas how to prevent this?

Hello rhinogroup!

I am really sorry to hear about this experience with our plugin! It seems indeed that might be related to the original ticket description error, so could you please answer a few questions as well:

1. Can you confirm that you are also seeing the same errors collected in debug log as Denis mentioned above? If so, are there any specific steps that you have done in order to reproduce these constantly? If you can share this with us, it would really help a lot.
   
   Example: Cron reschedule event error for hook: wsal_generate_reports_cron, Error code: invalid_schedule, Error message: Event schedule does not exist., Data: {“schedule”:”tenminutes”,”args”:[],”interval”:600}
2. Can you confirm the source of the image you shared with us so that we can understand how you discovered this?

4. Have you noticed any (bad) effects coming from the error on your site or plugin functionality?

5. Does your website use WordPress Cron (WP Cron) or a server-side cron alternative?

Looking forward to hearing back from you on this along with the answers to my questions. If there is any other sensitive data or information in your answers, feel free to share all the answers to my questions via email in order to avoid disclosing compromising data here on the forums.

Is this a new plugin installation when you have noticed this? Or have you noticed this after a plugin update?

I think this started happening after an update. We are using premium version 5.1.0

?Can you also describe a bit when this error gets generated? Are there any particular steps to reproduce this? Have you noticed the error only once, or did you notice it being generated constantly?

Not sure what triggers this because it’s a background action and we get these issues picked up in our logs.

Have you noticed any (bad) effects coming from the error on your site or plugin functionality?

I’d say filling up error logs are the bad effects.

Does your website use WordPress Cron (WP Cron) or a server-side cron alternative?

We use WP Cron.

I also got notice in our Sentry that there are N+1 queries, mainly:

UPDATE wp_2_options SET option_value = 'serialized data' WHERE option_name = 'cron'

SELECT wp_wsal_occurrences.* FROM wp_wsal_occurrences WHERE 1 AND ( ( ( site_id = '-1' ) )) ORDER BY created_on DESC LIMIT 5

and

SELECT * FROM wp_wsal_metadata WHERE occurrence_id = 375345 AND name = 'Users'

First one has some delete action from action scheduler as a preceding span, then this options update. The second one has a preceding span with this query:

SELECT option_value FROM wp_options WHERE option_name = 'wsal_adapter-connection' LIMIT 1

The last one has this query as arepeating span:

db.sql.query - REPLACE INTO wp_wsal_metadata (id, occurrence_id, name, value) VALUES (2530994, 451402, 'Users', 'a:0:{}')

Can you just let your engineering team to investigate this a bit more?

Thanks!
