from flask import current_app ImportError: cannot import name 'current_app'

This error message indicates that there is an issue with importing the `current_app` object from the `flask` module. This object is used to access the current Flask application instance, and is typically used in a context where the application instance is not available through other means.

There are a few possible reasons why you might encounter this error:

1. You may be importing `current_app` from the wrong module. Make sure that you are importing it from the `flask` module and not another module with a similar name.

2. You may be importing `current_app` before the Flask application has been created. `current_app` is only available when a Flask application context is active, so if you try to import it outside of a request or application context, you will get this error. Make sure that you are importing `current_app` from within a Flask view function, or from within a function that is called within a Flask view function.

3. There may be a circular import issue in your application. Flask applications can be prone to circular import issues if you're not careful about how you structure your code. If you're importing `current_app` from a module that also imports something from the module where your Flask application instance is created, you may run into this error. Try restructuring your code to avoid circular imports.

To resolve this error, you should check your code for the above issues and make sure that you are importing `current_app` correctly and in the right context. You may also want to review the Flask documentation on application context and request context to better understand how they work.
