Error exporting to MPX or MSPDI

When I try to export a file with 3 indentation, it producs an error:

Export failure. Failed subtask: Export project class java.lang.String cannot be cast to class java.lang.Integer (java.lang.String and java.lang.Integer are in module java.base of loader ‘bootstrap’)

And I am not able to export. I have exported other files withoud indentation and I am not sure if this is the problem and how I can solve it.

Many thanks in advance!!

Please share a sample project and the error log (Help > View log)

There is a text custom property named “ID” in this project. It matches a built-in MS Project task field “ID”, that has an integer type. I renamed your custom property to “ID_1”, and it exports fine now. The fixed file is attached.
