Error Troubleshooting

General troubleshooting steps

  • Try our online demo and see if you can reproduce the issue.
  • Check the console or network log and report any errors.
  • Enable and collect verbose logs (detailed below)

How to enable and collect verbose log

  1. Remove any old log files from
    • Windows C:\Windows\SysWOW64\Dynamsoft\DynamsoftServicex64_17\log or C:\Users\{UserName}\AppData\Roaming\Dynamsoft\DynamsoftService\log
    • macOS, Go > Applications > Dynamsoft > DynamsoftServicex64_17 > {installed version No.} > log
    • Linux, /opt/dynamsoft/DynamsoftService/log
  2. Set the log level
    • For only one client machine, add the line LogLevel=14 to DSConfiguration.ini on that specific machine.
    • For all client machines, set LogLevel to 1 in your code. This property should be set as soon as the WebTwain instance is created. For example, in the event Dynamsoft_OnReady
       function Dynamsoft_OnReady() {
         DWObject = Dynamsoft.DWT.GetWebTwain("dwtcontrolContainer");
         DWObject.LogLevel = 1;
       }
      
  3. Reproduce the issue

  4. Zip the log files and share with Dynamsoft Support Team via email.
    • On Windows, the log files are in C:\Windows\SysWOW64\Dynamsoft\DynamsoftServicex64_17\log or C:\Users\{UserName}\AppData\Roaming\Dynamsoft\DynamsoftService\log
    • On macOS, the log files are in Go > Applications > Dynamsoft > DynamsoftServicex64_17 > {installed version No.} > log
    • On Linux, the log files are in /opt/dynamsoft/DynamsoftServicex64_17/log
