To fix this first you need to create an integration account, which is a separate Azure resource that provides a secure,scalable, and manageable container for the integration artifacts that you define and use with your logic app workflows. You can click on Create new Resource and search for integration account. You need tp provide the name and location. You need to choose the pricing tier according to your requirements, for demo purposes I am choosing the Free tier.
Once it is created, you need to open the Azure Logic App and select the Workflow settings menu, and from the Workflow Settings, choose the Integration account you created.
Here few helpful links which helps you to choose the integration account.
Happy Programming 🙂
