What to perform when using CV Local Server (UiPath.ComputerVision.LocalServer package), Error "Response from server is not valid" is thrown?
Root Cause:
- Antivirus blocks the UiPath.CVLocalServer.Host.exe file or the prerequisites are not installed
- Sometimes, with some OCRs, some elements on the screen are not detected which can lead to this behavior.
Resolution: Refer to the troubleshooting steps on About the local server package UiPath documentation on this error. If the issue is not solved after the above steps,
- Check if it is an issue with OCR
- Use CV ScreenScope and OCR of choice
- Use a CV activity of choice and check if the element is detected. If not, try to switch to a different OCR and see if the element can be detected
- Eg: When using UiPathScreenOCR, if the body part is not detected as editable, it is not possible to do a type into. After changing the OCR to Tesseract, it might display as editable.
