CasperJs Catch Timeout and Restart Process

Question: How to restart a casperjs process on a tiemout error

Problem I run a crawler which sometimes times out:

[error] [phantom] Wait timeout of 5000ms expired, exiting.
Wait timeout of 5000ms expired, exiting.
Error: TypeError: 'null' is not an object (evaluating 'document.querySelector('#identify tbody tr:nth-of-type(' + (current * 2 + 2) + ') div.details>div').innerHTML')

Not working solution I put all my casper script into a function which I want to restart on the timeout event:

runCasper = () ->

  console.log ">>>>>>>>>>>>>>>>>>STARTING CASPER<<<<<<<<<<<<<<<<<<<<<<"

  #Starts Casper and Takes a Snapshot
  casper.start(url, () ->
    self = this
    this.viewport(1024, 768, ()->
      self.capture('screenshotsKv/start.png')
    )
  )


  #Iterate through all 
  .eachThen(plz, (response) ->
    lots of code


  .on( 'wait.timeout', (msg) ->
    this.echo( 'Error: ' + msg, 'ERROR' )
    log.aborted = log.aborted.concat(log.last + ' ' + new Date().toString())
    functionsFiles.saveLog(log)
    self.capture('screenshotsKv/' + log.last + ' ' + new Date().toString() + '.png')
    runCasper()
  )


  #Save all results into the database
  .run(() ->
    this.exit()
  )

#Starts Casper
runCasper()

I also tried step.timeout but both don't trigger the restart.

Possible reasons (imho):

  • because the whole process terminates including the .on listener?
  • the listener is wrong?
  • the timeout is from phantom and the listener is limited to casperjs?
