I have ng2-file-upload installed in my angular project and I am using angular 16. The following is blocking me
This likely means that the library (ng2-file-upload) which declares FileUploadModule is not compatible with Angular Ivy. Check if a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the library is expected to be compatible with Ivy.
I faced similar issue while migration. I used ng2-file-upload version 3.0.0 which solved my issue. But make sure to add url in fileUploaderOptions which is made mandatory.
