Error in stack file via api produces no error in api output

[alphaDev23]

Portainer 1.23.0. An error created by including a space before "version" on the first line produces no error in the api output. Instead, no services are created.

Expected result. An error via the api output should inform the user that the stack file format is incorrect.

@alphaDev23 I was not able to reproduce this while doing the following api call against the stack creation API 10.1.3.46:9000/api/stacks?endpointId=3&method=string&type=1

body: {
    "Name": "test",
    "SwarmID": "ximybf7av6fmjkffd43n1f4iwp",
    "StackFileContent": " version: '3'\nservices:\n  test:\n    image: nginx",
    "Env": []
}

Could you please elaborate on the api call you are making and provide an example request body you are sending that includes the space before version?

e.g. Stack definition starts with (space before 'version'):

version: '3.4'
services:
...

@alphaDev23 What are your reproduction steps as I cannot recreate this. Every time I try, the stack is still created.

I have tried:

• Api call against the stack creation API 10.1.3.46:9000/api/stacks?endpointId=3&method=string&type=1

body: {
    "Name": "test",
    "SwarmID": "ximybf7av6fmjkffd43n1f4iwp",
    "StackFileContent": " version: '3'\nservices:\n  test:\n    image: nginx",
    "Env": []
}

• Stack creation through the UI with different variations of the YAML:

version: '3.4'
services: 
 test:
   image: nginx

 version: '3.4'
services: 
  test:
    image: nginx

The api call and the 2nd UI examples you describe are correct. I had produced the error via the api call.

Re-opening this as I have just been able to reproduce this on 1.23.2 in the following ways:

Via UI

1. Create stack in UI with following yml

 version: '3.4'
services: 
  test:
    image: nginx

2. See that there is a syntax error shown in the editor but its accepted anyway
   

3. See that no services are deployed

Via API

1. Make API call with space at start of the stack

{
    "Name": "test",
    "SwarmID": "j7zp2f0ly9pl0laf05g6mrlz8",
    "StackFileContent": " version: '3.4'\nservices: \n  test:\n    image: nginx\n",
    "Env": []
}
2. See call succeeds with 200 OK but no services are deployed
