It might be helpful to run `TF_LOG=DEBUG pulumi up --debug` to see what the actual API request to AWS looks like.

Thanks, I let you know the output. Was trying to find a debug feature like that in the pulumi commands options.

<@UDEJ1F5SQ> where should I expect to see the debug logs?

forgot to add `--debug` . I'll send you the print shortly

Here is one of the logs
```   pulumi:pulumi:Stack booksloth-import-dev running debug: RegisterResource RPC prepared: t=aws:batch/jobDefinition:JobDefinition, name=booksloth-import-dev-importLauncher-job-definition
    pulumi:pulumi:Stack booksloth-import-dev running debug: RegisterResource RPC finished: resource:booksloth-import-dev-importLauncher-job-definition[aws:batch/jobDefinition:JobDefinition]; err: null, resp: urn:pulumi:dev::booksloth-import::aws:batch/jobDefinition:JobDefinition::booksloth-import-dev-importLauncher-job-definition,,__defaults,,,,,,,containerProperties,,,{"image":"import/launcher","command":["node","index.js"],"memory":2000,"jobRoleArn":"arn:aws:iam::062155736059:role/booksloth-import-dev-importLauncher-job-role","environment":[{"name":"NODE_ENV","value":"dev"},{"name":"APP_VARS","value":"{\"resourcePrefix\":\"booksloth-import-dev\",\"retry\":{\"retires\":3,\"minTimeout\":200,\"maxTimeout\":1000}}"},{"name":"BOOKSLOTH_API_VARS","value":"Calling [toJSON] on an [Output&lt;T&gt;] is not supported.\n\nTo get the value of an Output as a JSON value or JSON string consider either:\n    1: o.apply(v =&gt; v.toJSON())\n    2: o.apply(v =&gt; JSON.stringify(v))\n\nSee <https://pulumi.io/help/outputs> for more details.\nThis function may throw in a future version of @pulumi/pulumi."}]},name,,,booksloth-import-dev-importLauncher-job-definition,parameters,,,,,BATCH_MESSAGE,,,Empty,__defaults,,,,,,,retryStrategy,,,,,__defaults,,,,,,,attempts,,3,tags,,,,,Environment,,,development,__defaults,,,,,,,timeout,,,,,__defaults,,,,,,,attemptDurationSeconds,,3600,type,,,container,,```

Just saw that a variable wasn't been properly converted to string. Made the fix, and still same results

What is `bookslothApiVars` in your code? It looks like that needs to be `.apply` as well.

You can apply multiple values with `.all` - e.g. <https://www.pulumi.com/docs/intro/concepts/programming-model/#all>.

Found the problem. I first fixed the apply with pulumi all. it fixed the `bookslothApiVars` value. Stlil had the same problem. The issue was the container image.  I was using this to build the image:
`const img = awsx.ecs.Image.fromPath('import/launcher', "../");` and it wants and image from a ecr repository.  So building the image like this:
```const img = awsx.ecr.buildAndPushImage(`${config.prefix}-${serviceName}-img`, '../', {
  tags: {
    Environment: config.env,
  },
})```
and passing img.imageValue to containerProperties fix it.

It wasn't obvious to me to determine this because there is no interface for the `containerProperties`  It would be helpful to add it, since I had to go to <https://docs.aws.amazon.com/batch/latest/APIReference/API_RegisterJobDefinition.html|API_RegisterJobDefinition> to check the format.
