Hello,

I want to publish the demo2025 project.
I have ANM 2025.4 (registered); database created successfully, but I get this error during project generation:

I have removed from advanced settings examples with SAML, external auth provider examples, etc.

Can you generate with another project file (or a new project file)?

If it is specific to this project file, you may need to send your project file to the support email for checking.

Yes we have other projects started from scratch.
Actually only demo2025.agx project fails this way

No problem in generating the demo project. Make sure that you have specified a correct destination folder.
