error message for email automation

[LaCollection]

Hello there, 

I am getting this error on one of my automation emails: "Failed to query data for subsequent steps: Missing resource for customer." I am unsure what this means can anyone advise? It ran this past Sunday and seemed not to have any errors. Then it tried to run again on Tuesday and seems to have errors. I don't recall making any changes though.

Hi, @LaCollection.

Thanks for posting to the Shopify Community!

This error message may indicate that the automation process attempted to access or use customer data that was not available or could not be retrieved. This can happen in various scenarios, such as when the customer data is deleted, inaccessible, or not properly linked. 

I would like our authenticated Support to take a more detailed look into the issue and troubleshoot effectively. Since we do not have authentication tooling or access to your admin through the Community Forum, we recommend creating a support request through the Shopify Help Center.
