## Description of the issue

Error message ‘The build configuration cannot be found in detox.configurations[“${program.configuration}”]’ when running under a standard Detox configuration. The project structure has not been modified, it is also working locally. Have tried explicitly passing the config to both the `build` and `test` as suggested elsewhere. Can anyone help? Thanks.

## Environment:

Bitrise XCode 9.4.x MacOS 10.13

**Which build Step causes the issue and which version of the step?**

detox build & test:

detox clean-framework-cache && detox build-framework-cache

detox build -c ios.sim.debug

detox test -c ios.sim.debug --cleanup

note, I am specifying the config in package.json like this

“detox”: {  
“configurations”: {  
“ios.sim.debug”: {  
“binaryPath”: “../ios/build/Build/Products/Debug-iphonesimulator/testapp.app”,  
“build”: “xcodebuild -project ../ios/testapp.xcodeproj -scheme testapp -configuration Debug -sdk iphonesimulator -derivedDataPath ../ios/build”,  
“type”: “ios.simulator”,  
“name”: “iPhone 7”  
}  
},  
“specs”: “./detox/base/”,  
“test-runner”: “jest”,  
“runner-config”: “./detox/config.json”  
}

## Reproducibility

- _Does a “Rebuild” help? (You can trigger a rebuild from the Build’s page, by clicking the “Rebuild” button in the top right corner of a finished build)_ : NO
- _Does a rebuild without caches help? (You can remove the `Cache:Pull` and `Cache:Push` steps temporarily to not to use the cache, or [you can delete all the caches on the `Settings` tab of the app](http://devcenter.bitrise.io/caching/about-caching/#downloading-and-deleting-caches)._ : NO
- _Does the issue happen sporadically, or every time?_ :
- _Does upgrading the build Step to the latest version help?_ : NO
- _When did the issue start?_ : Yesterday

### Local reproduction

_Can it be reproduced on your own Mac/PC by following our [local debug guide](http://discuss.bitrise.io/t/how-to-debug-your-build-locally-it-works-on-my-mac-pc-but-not-on-bitrise-io/392)? Please follow at least the first section (“Testing with a full clean git clone”) to make sure to test the state of the code what [bitrise.io](http://bitrise.io) will get when it does a git clone in the clean environment! If possible please note which sections you tried._
