Our instance used the new feature Column Power-Fx
When we manually export then import to other instances it ok.
+ When we used Solution Packager to unpack the zip files, we saw the new in the Entities\xxxx\Formulas\yyyy-FormulaDefinitions.yaml file.
+ When we used Solution Packager to pack to folder (Azure DevOps), to solution files, the file *.yaml NOT include in the .zip file
And then when we import, we get the error:
Attribute import: FormulaDefinition file is missing from import zip file: FileName: /Formulas/yyyy-FormulaDefinitions.yaml</Message>
I think this is a bug from Solution Packager 🙂
