Significant Delays in Shopify Flow Action Webhook - Started Around September 11, 2023

[kogai]

I'm developer of the Public App.

We are providing an Action for Shopify Flow.

However, I've noticed that the Action webhook from Shopify seems to be significantly delayed.
For example, if the Trigger was executed at 12:00 AM with the flowTriggerReceive mutation, the Action webhook often arrives at 12:10 AM or later.

I am not sure when such issues are began, but I have been receiving complaints from merchants since around September 11, 2023.

When we investigated the logs of our app server, we found that webhooks taking more than 3 minutes to receive the Action occur at a rate of about 40 to 50 times per hour.

We know that it is not defined expectation length of time takes workflow to complete.

But such that to take long length of time seems odd a bit.

Is the Shopify's dev-team aware of this issue?

If necessary for investigation, I can provide multiple action_run_id of the delayed Actions.

Hi, we aren't aware of any incident or broader slow-down of webhooks or Flow workflows There are many things that could happen that would result in a workflow taking 10 minutes to run. There could be transient errors if they are calling an API, they could have wait steps, etc. So we would need to link to a few workflow runs to troubleshoot. Also, I think you are saying that the workflows involve a trigger that your app sends and an action that your app receives. If that is not the case, please clarify. 

You can also contact us via email if you need to provide more sensitive information at flow-connectors-dev@shopify.com

Hi Paul, thanks for replying.

As you said, I think it would be easier to understand the situation if we'll provided a specific workflow and action_run_id, so I'll email the email address you gave me.

UPDATE:

We've discussed about the issue via email with Paul, then identified there were indeed some performance issues exist on some system of Shopify Flow, and I'm happy to say it's already resolved.

Thank you to Paul for the support and dev-team !
