Hi @lowly2005 thank you for your feedback.

Have you proceed to an upgrade of the forest-express-sequelize package ?

oscar6654 · September 1, 2020, 8:50am

@Arnaud_Moncel I am getting the same problem. I tried npm update forest-express-sequelize.
I also tried using yarn instead of npm, same issues…

Hi @oscar6654 welcome to our community.

What is your version of node please ?

oscar6654 · September 1, 2020, 9:14am

v14.2.0.

Not sure if I am installing/setting forest admin correctly. I am using rails.
this is my folder structure…

Arnaud_Moncel · September 1, 2020, 9:21am

Ok guys we introduced a regression on latest release of forest-express-sequelize.
You can easily fix your problem by fixing the version of this package to

"forest-express-sequelize": "6.3.6",

I will keep you update when the fix was released.
Thank you again and sorry for the inconvenience.

Arnaud_Moncel · September 1, 2020, 12:52pm

Hey guys a fix has been released you can use

"forest-express-sequelize": "^6.0.0", / "6.3.8",
