No method named `GetColumn’ in class java.lang.Boolean

My app was running perfect earlier, but since when Kodular gets updated I’m facing an error.

Please help me to resolve this

You have wrong blocks for get column.

Can you show us your blocks?

Using Kevin extension or dictionary method for getting values from airtable?

is there a problem

You should recast your project. It seems that there are some extension in your project that need migration.

What are extensions and how do you change them

See the App Inventor Extensions document
only the extension developers themselves can change their extensions
