Cannot update _User, _Role, _Product, _Installation, _Session via Schemas API

[ntloc592]

• When I try to update _User, _Role, _Product, _Installation, _Session via Schemas API
• Result:
  {
  "code": 136,
  "error": "field 'field name....' cannot be added"
  }

This should be fixed by #797

[Marco129]

@drew-gross #797 did not fix this bug.
Perhaps is another problem in function buildMergedSchemaObjectof Schema.js

[drew-gross]

OK, thanks for the heads up. Reopening.

Merged #811

I try to update system scheme with lasted version via Schemas API, but I can not do that

• Result:
  {
  "code": 136,
  "error": "field 'field name....' cannot be added"
  }
• In Schema.js
  • var sysSchemaField = Object.keys(defaultColumns).indexOf(mongoObject._id) === -1 ? [] : Object.keys(defaultColumns[mongoObject._id]);

==> This is not working with System schema.
==> 'mongoObject._id' is alway 'undefined', so 'sysSchemaField' is alway []

Can you post the current contents of your _SCHEMA collection and a curl that demonstrates the issue? Also make sure you are using the latest version of Parse Server (2.1.4)

I make sure using lasted version 2.1.4
I try to update System Schema via API

• http://localhost:1337/schemas/_User - POST method
• JSON data post
  {
  "_ApplicationId": "appId",
  "_ClientVersion": "browser",
  "_MasterKey": "masterKey",
  "_InstallationId": "308310ea-6516-75bb-bcf7-3c85fbf0ec2f",
  "_method": "PUT",
  "className": "_User",
  "fields": {
  "test_system": {
  "type": "String"
  }
  }
  }
• Result:
  {
  "code": 136,
  "error": "field username cannot be added"
  }

[Marco129]

Oh! My bad...
I assumed there will be a _id just like some of the test cases
Will provide bugfix PR asap

Thanks for this work!
