The 'ListCallbackUrl' API is not supported by triggers of type 'ApiConnection' in Blob triggered Standard Logic App Workflow

Question

We have bunch of workflows which connect to different containers in a storage account and get triggered by a new file added in any of them. These workflows used to work fine before we implemented VNet-Integration and connected the concerned storage account with a private endpoint to the same VNet. The connectivity between the workflows and storage account is established but for some reason we are getting these errors on the trigger in all the workflows now-

The error in the trigger history is this -

    }
}

And the network trace gives this 400 error-

 code: "ApiNotSupported"
    message: "The 'ListCallbackUrl' API is not supported by triggers of type 'ApiConnection'."

Does anybody know what could be the reason for this error and how to resolve it? Thanks in advance.
