EMS: Error occurred during transfer.

drichter · ‎Nov 22, 2019

Hey,

I try to evaluate the possibilities of the EMS Stuff. Today I try the file transfer functionality with no success.

I have a device where the ems runs on (as gateway) and a twx instance on a ec2 in aws.

My config.json lookes like this:

{
  "ws_servers": [{
  "host": "xxx.xxx.xxx.xxx", (TWX IP)
  "port": 443
  }],
  "appKey": "xxxxxxxxxxxxxxxxx",
  "logger": {
    "level": "INFO",
    "publish_directory": "/microserver/logs",
    "publish_level": "INFO",
    "max_file_storage": 2000000,
    "auto_flush": true
  },
  "http_server": {
    "host": "xxx.xxx.xxx.xxx", (IP EMS runs on)
    "port": 8000,
    "ssl": false,
    "authenticate": false
  },
  "ws_connection": {
    "encryption": "ssl"
  },
  "certificates": {
    "validate": false
  },
  "tunnel": {
    "buffer_size": 8192,
    "read_timeout": 10,
    "idle_timeout": 300000,
    "max_concurrent": 4
  },
  "file": {
    "buffer_size": 8192,
    "max_file_size": 8000000000,
    "virtual_dirs": [
      {"other": "/microserver/other"},
      {"tw": "/microserver/tw"},
      {"updates": "/microserver/updates"}
    ],
    "staging_dir": "/microserver/staging"
  },
  "auto_bind": [{
    "name": "EMSGatewayThing",
    "gateway": true
  },
  {
    "name": "OtherEdgeThing",
    "host": "1.0.1.2",
    "port": "8001",
    "protokol": "http",
    "gateway" : false
  }
  ]
}

My lua-script looks like this:

scripts.log_level = "WARN"

scripts.script_resource_ssl = false
scripts.script_resource_authenticate = false

scripts.EdgeThing = {
  file = "thing.lua",
  template = "YourEdgeThingTemplate",
  scanRate = 120000,
  sw_update_dir = "/microserver/updates"
}

I try to send a small simple txt-file from SystemRepositoy to the "other"-folder on the edge device via the copy-service of the FileTransferSubsystem.

After the timeout-time ends I get a result table with not much information what went wrong. In Application Log i get this:

[context: Error occurred during transfer.: service execution failure resultCode=STATUS_GATEWAY_TIMEOUT: job=TransferJob [tid: adf44aaa-df36-463d-88d3-3f5d1d066e62, sourceRepo: SystemRepository, sourcePath: /file-transfer-test.txt, targetRepo: OtherEdgeThing, targetPath: other/file-transfer-test.txt, partPath: __staging__/OtherEdgeThingother.file-transfer-test.txt.part, sourceChecksum: , targetChecksum: , state: ACTIVE, code: 202, message: Transfer request accepted, isAsync: false, isRestartEnabled: true, isComplete: false, bytesTransferred: 0, blockcount: 0, blocksize: 8192, size: 35, maxsize: 100000000, transferTime: 0, transferControl: platform, reservationId: , user: david.richter, isQueueable: false, enqueueTime: 0, enqueueCount: 0, metadata: null, Job [id: adf44aaa-df36-463d-88d3-3f5d1d066e62, lastTouch: 1574415465008, timeout: 30000, TimedLock [createTime: 1574415464898, signalTime: 0, duration: 0, signaled: false]]]]

This says the transfer request was accepted (202) but no data was transfered.

On my edge device a I have a new created .part file (OtherEdgeThingother.file-transfer-test.txt.part) with size of zero.

I have no idea what went wrong. Both devices (EMSGatewayThing and the OtherEdgeThing) are connected under remote things

Hi @drichter

Can you please add the host and port used by the http_server configuration to auto_bind configuration?

Following article refers the resolution and provides a sample config.json that can be referred

Please do let us know if this helped resolve the issue.

Hi @nishanair,

I add the host and port to the first element of the auto binding group, with the same ip and port like in http_server but I get the same error.

If you couldn't solve the problem try these changings.

"http_server": {
    "host": localhost or 127.0.0.1,
    "port": 8080,
    "ssl": false,
    "authenticate": false
  },
"auto_bind": [{
    "name": "name of your thing",
    "port": 8080
}]
