How to resolve the Microsoft.Azure.Workflows.WebJobs.Extensions error for the Aure Logic app

I’m trying to deploy an Azure standard Logic app with Private endpoints using Terraform. It creates the resources and successfully completed without an errors but it is displaying below error when trying to access the logic app from the portal and also workflow creation is also failing.

Microsoft.Azure.Workflows.WebJobs.Extensions: Could not load type ‘Microsoft.Azure.WebJobs.Host.Listeners.IListenerDecorator’ from assembly ‘Microsoft.Azure.WebJobs.Host, Version=3.0.38.0, Culture=neutral, PublicKeyToken=’.

How can I fix the issue?

Terraform code:

    Use below modified terraform code for deploying a standard Logic app with Private endpoints.

    I got it resolved after updating the LogicApp (Standard) Configuration setting "AzureFunctionsJobHost__extensionBundle__version"

    from default versions range

    [1.*, 2.0.0)

    to specific version

    [1.31.12]

    For future deployments to prevent overwriting the changes in app, Extension bundles file shall be updated in the project/template code base.

    Some more details about upgrading the LogicApp to use Functions version 4 shall be referred here Azure Logic Apps Standard now supports Azure Functions v4
