Uipath screen OCR Error endpoint beta is wrong?

i tried use read pdf with Uipath screen ocr engine yesterday but i have this problem Message: Error performing OCR: Error al enviar la solicitud. ScreenOCRErrorRunningEngine
looks like a error of endpoint or something, another engines like abbyy cloud works fine, i used to use this engine before without problem

Log error:

@ovi do you know if the preview period of uipath screen ocr is ended? because the activity just stopped working? in the update the activity doesn’t have an endpoint like the previous one

Exact same error here. Process was running great using the UiPath Screen OCR engine preview and just stopped working on 1/23.

Was using 1.0.0-preview with https://beta-ocr.uipath.com/v1/images:annotate as the endpoint. Updated to 1.2.0-preview and like @luchovelez no endpoint but above endpoint doesn’t work either.

exactly this is the problem, i was ready for release a bot a production but this problem force me to use omnipage OCR but is not close to uipath screen results in time and precision

Hi everyone,

Please see my post here :slight_smile:

what is the new endpoint?

You don’t need any, simply provide the API key and it should work.

the new endpoint is required but which is ?

Judging form your screenshot:

You placed the API Key in the wrong box. Leave the Endpoint field blank and put your key in the ApiKey field :slight_smile:

If I leave the End Point as blank means it throws error.

do you have the last version of activity ?

Yes, It’s the latest one.

what is the last endpoint

I have the same error, again… The endpoint, previously https://beta-ocr.uipath.com/v1/images:annotate, don’t work since 1 week i think (“Origin DNS error” when i open manually).
Thanks for advices.

It’s work !
Solution :

  • Generate API Key “Computer Vision” in Portal UiPath (admin>Licences>OtherLicences). More info in UiPath Screen OCR: Now in Public Preview!. This step is required (previous week : it was worked with the preview endpoint without API Key)
  • Manage Project, and set endpoint : https://ocr.uipath.com/ and API Key
  • Restart UiPath Studio !
  • Test !
