Buildspec file with build-graph doesn't do anything

Question

My [buildspec file](https://github.com/evenflow58/monster-of-week/blob/authorizer/infrastructure/pipeline/buildspec-build.yaml) looks like this and doesn't seem to do anything. I'm guessing that it's not finding the other build files but I'm not sure why. I don't see anything in CloudTrail either but maybe I'm just missing it.
```
version: 0.2

env:
  shell: bash

batch:
  fast-fail: false
  build-graph:
    - identifer: api
      buildspec: infrastructure/pipeline/api-build.yaml
      ignore-failure: false
      debug-session: true
    - identifer: all
      buildspec: infrastructure/pipeline/project-build.yaml
      ignore-failure: false
      debug-session: true
      depend-on:
        - api
```
Build output:
```

Update: I tried using an inline build spec and I'm still not seeing any difference.

              - echo "nested build"
```

Accepted Answer

It looks like my issue was in my pipeline, not the actual build spec. When building the Build stage I didn't add the `BatchEnabled` property to the Configuration section. I got it working but updating my step to the following.
```
Stages:
        - Name: Build
          Actions:
          - Name: Build
            ActionTypeId:
              Category: Build
              Owner: AWS
              Version: 1
              Provider: CodeBuild
            Configuration:
              ProjectName: !Ref BuildRunner
              BatchEnabled: true
```
I also had to update the service role with the appropriate batch build permissions and I had a typo in my build spec file (identifer -> indentifier)

Answer

Can't you see the log output from the batch build screen instead of the build log?  
Probably logs are output to CloudWatch Logs for each phase (api,all).  
If you open the batch history from the CodeBuild build project, you can check the status and other information.  
Specifically, the screen in the following image.  
I don't use batch builds in my environment, so I don't see anything, but if it is running, it should show something.
