Unable to save modeler diagram

I'm unable to save a modeler diagram after amending that previously worked without any problems. I'm now getting an error message that states " Object Reference is not set to the instance of an object" and the diagram will not save. Please advise

Dear Dyfed,

This error message is usually prompted when there are problems with the instances of your process. Can you please share your model with us? Thanks.



I am also having this problem everyday using Bizagi.

I also cannot share the model I am working because of confidential content.

That being said, I would never recommend Bizagi for professional use.


Dear Roberta,

We are very sorry that you are experiencing these inconveniences with Bizagi. However, it is important to know that in the majority of the cases, that error is related to modeling problems. I will attach a recommendation for all the beginner/intermediate users of Bizagi. We would like to help you with the "confidential content" issue, it is probably related to misconfiguration and not with the quality of the product. Thanks for your understanding.

Best Regards.
