@rsa408 This is just an example repo so wrong place to post for help. Try Loopback repo or stackoverflow.com. Please make a git repo to demonstrate the issue as it makes it much easier to quickly spot your issue.

Hi
I am appreciated for your response. I am really confused where is my problem. ths over 5 days that I try to find the problem. I made a special git repo for this problem(https://github.com/RsaLB4/test)could you please check it? I tried with different datasourcess even memoryDB but in all the ways I got the same result.

sample codes ith memoryDB are working fine after changing them to MongoDB everything goes wrong on my machine. I tried to fresh windows npm packages everything but the result was even worse of before.

Thanks

The problem is an inconsistency between your model and the user controllers request body where one says include an id and the other says omit the value. Typically you would not supply an id, so I'd recommend that you set the user model id to be a string(for mongodb) that is not required and generated: true. This would (after running migrate) allow the database to provide a unique id.

For your project though to submit an id you need to alter the controller. Change schema: getModelSchemaRef(User, {exclude: ['id']}), to schema: getModelSchemaRef(User),

If you have further issues I'd recommend not posting here, but in the aforementioned locations.

Thanks @dougal83. I've cross-posted your comment in loopbackio/loopback-next#3645. Let's continue the discussion over there (in the right repo). Thanks!
