csantanapr opened a new issue #128: Whisk CLI fails with a `cannot invoke action` error if 1 of your keys is named `response` URL: https://github.com/apache/incubator-openwhisk-cli/issues/128 @sroorda commented on [Fri Sep 15 2017](https://github.com/apache/incubator-openwhisk/issues/2757) ## Environment details: * local deployment, vagrant, native ubuntu, Mac OS, Bluemix, ... * version of docker, vagrant, ubuntu, ... Deployed to Bluemix api.ng.bluemix.net It appears that if you invoke your Cloud Function via the CLI it will fail with `error: Unable to invoke action 'nestedDictionaryError': The connection failed, or timed out. (HTTP status code 200)` if you include a key labeled `response` in your output. ## Steps to reproduce the issue: Create the following Cloud Function in python ``` def main(args): result = {'message': 'error result', 'response': {'key1': 'value1','key2': 'value2' }} if args and args['resultType'] and args['resultType'] == 'error': return {'message': 'error result', 'response': {'key1': 'value1','key2': 'value2' }} else: return {'message': 'error result', 'not_response': {'key1': 'value1', 'key2': 'value2'}} ``` ## Provide the expected results and outputs: ## Provide the actual results and outputs: Fails ``` wsk action invoke --result nestedDictionaryError --param resultType "error" error: Unable to invoke action 'nestedDictionaryError': The connection failed, or timed out. (HTTP status code 200) Run 'wsk --help' for usage. ``` Works ``` wsk action invoke --result nestedDictionaryError { "message": "error result", "not_response": { "key1": "value1", "key2": "value2" } } ``` Even if response is reserved we should get a better message than that. ## Additional information you deem important: * issue happens only occasionally or under certain circumstances * changes you did or observed in the environment
