Error Troubleshooting
Error Message - Source has nothing to capture
Symptom
On Linux, calling ErrorCode/ErrorString after a scan could return code 1029 with “Source has nothing to capture,” even though scanning completed successfully.
Solution
The message was cosmetic only. It was fixed in Dynamic Web TWAIN 18.0. On 18.0 or later, no action is required. If you are on an earlier version and see 1029 despite a successful scan, you can ignore it or upgrade to 18.0+ to remove the message.
