Error streaming dataset flow with power BI

I'm trying to create a flow in the azure to do data input of some # in the twetter, I created my streaming dataset without problems I set up my flow but at the time of the update the following error occurs:

("error": {
    "code": 500,
    "message": "{\r\n  \"error\": {\r\n    \"code\": 500,\r\n    \"source\": \"msmanaged-na.azure-apim.net\",\r\n    \"clientRequestId\": \"aeb5d2ce-df32-4096-8fba-09a7ad35e072\",\r\n    \"message\": \"BadGateway\",\r\n    \"innerError\": {\r\n      \"error\": {\r\n        \"code\": \"RealTime_PushRowsInvalidJson\",\r\n        \"pbi.error\": {\r\n          \"code\": \"RealTime_PushRowsInvalidJson\",\r\n          \"parameters\": {},\r\n          \"details\": []\r\n        }\r\n      }\r\n    }\r\n  }\r\n})

  

 

 

Already tried to create a flow again but always the same badgateway error
