Can't include the Cropper.js module into my Jinja page
I am using your dashboard and it's working great so far. However, now I ran into an issue;: To add image cropping support to one of my Flask/Jinja pages (based on your dashboard framework) I followed the Cropper.js usage example on GitHub, added the CSS link to the <head> of my HTML page (between the {% block stylesheets %} and the {% endblock stylesheets %} statements) and added the following to the <body> of my page (between the {% block javascripts %} and the {% endblock javascripts %} statements):
<script src="/static/assets/js/plugins/cropper.min.js" type="module"></script>
<script>
import Cropper from "cropperjs";
const image = document.getElementById('crop_image');
const cropper = new Cropper(image, {
aspectRatio: 1 / 1,
crop(event) {
console.log(event.detail.x);
console.log(event.detail.y);
console.log(event.detail.width);
console.log(event.detail.height);
console.log(event.detail.rotate);
console.log(event.detail.scaleX);
console.log(event.detail.scaleY);
},
});
</script>The cropper.min.js file can be found, as I see in the Firefox 77.0.1 browser console.
However, I do get the following error message in the console:
SyntaxError: import declarations may only appear at top level of a module
at the first line of the JS <script>:
import Cropper from "cropperjs";I found in this StackOverflow thread that this error might come in Firefox from missing type="module", but as you can see I do have this in my code. Any other ideas what could be wrong here?
Template issue with latest SQLAlchemy and flask_sqlalchemy
Hi there,
flask_sqlalchemy 2.4.4
SQLAlchemy 1.4.0 installed by flask_sqlalchemy
The following error pop from console:

This is the same problem for all appseed template. Apparently Binary is not implement anymore in latest version of flask_sqlalchemy.
from sqlalchemy import Binary, Column, Integer, String
...
password = Column(Binary)
If you replace with String or LargeBinary in models.py another error appear as well, related here: pallets-eco/flask-sqlalchemy#932
In order to use the template you should force to an older version in requirements.txt:
flask_sqlalchemy==2.4.1
sqlalchemy==1.3.17

Gunicorn does not start the Flask app with DEBUG set to False
I deployed our application based on your Gradient Able framework to our server, setting DEBUG=False in the .env file. However, after starting the app via gunicorn the global DEBUG config option in the Flask app is still set to True. It does work, however, when hard-coding the value in run.py, instead of the following line:
DEBUG = config("DEBUG", default=False)
Is this a bug or a feature?
