यह पता लगाने की कोशिश क्यों है 

  get '/ json_test' do j = '{ "Key1": "val1"} 'JSON.parse (j) एंड

 आंतरिक सर्वर त्रुटि  
 एरे को स्ट्रिंग में परिवर्तित नहीं किया जा सकता   
 प्रिमी मणि का उपयोग करके मैं पार्सिंग से पहले ब्रेकपॉइंट को हिट करने में सक्षम हूं। वहां से मैं JSON.parse (j) को कॉल कर सकता हूं और यह ठीक काम करता है।

  get '/ json_test' do j = '{"key1": "val1"}' 'JSON.parse (j) 200 अंत
