The error
TypeError: Cannot read properties of undefined (reading 'component')in the SaaS Tenants page is typically caused by a problem in the Angular extensible table component, often due to a missing or misconfigured template, or an unexpected data structure returned from the backend.This can happen if the tenant data returned from the backend is missing expected fields, or if a custom column/component is referenced in the table configuration but not properly registered or implemented.
To resolve:
- Ensure your backend API is returning all required fields for each tenant, especially those referenced in the table columns.
- If you have customized the SaaS module or the tenants table, verify that all custom columns/components are correctly implemented and registered.
- If you recently updated ABP or the SaaS module, clear your browser cache and restart your application to ensure all assets are up to date.
- Check for any breaking changes in the ABP SaaS module documentation for your version.
If you are using the commercial SaaS module, refer to the official documentation for the correct structure and customization points:
If the issue persists after these checks, review the browser network tab to inspect the actual data returned from the API and compare it with the expected structure.

Hello, I have tried to produce the problem using the specific
9.0.3version. However, I did not encounter the same problem. Could you clarify whether you have added a customization or make changes in your template to impact this part? You can also send a minimal reproducible example to this e-mail address if you prefer: sumeyye.kurtulus@volosoft.com. -

If you have replaced some components in the related part, this may cause this problem. You can follow this guide. https://abp.io/docs/latest/framework/ui/angular/component-replacement
Angular ui extensions may also cause this if you missed a point here https://abp.io/docs/latest/framework/ui/angular/extensions-overall
If this is not the case, I can assist you further based on the details you could give since it is not producible on a generated app.

Hello,
We did not have any component replacements or extensions. To confirm, can we check the versions of angular/lepton we should be on? This is our package.json file from Angular for the dependencies.

Hello again, Thank you for providing extra details on your problem. I have also tried using the version
9.2.x. However, I cannot produce the same problem. That would be the best if you could send a minimal reproducible example to this e-mail address: sumeyye.kurtulus@volosoft.com. Thank you for your cooperation. -

Ok, let us try to create a minimal reproducible example on a generated app and get back to you on this. Can i confirm we should follow this guide to start an abp app on a different older version? Starting a new solution now will just put us on the latest ABP Version 9.3 https://abp.io/docs/latest/studio/working-with-suite
