@pinussilvestrus Can I take up this issue?

[pinussilvestrus]

Of course! Feel free to open a PR and/or ask for help if you need some 🚀

[imrishabh18]

What should be the text for the error message then?

[pinussilvestrus]

There is a hint in the issue description

Error message reads "diagram.dmn" is not a BPMN file.

Despite, you can always come up with another solution if you think there is something better.
