Saving error occurs during UiPath Document Understanding validation

Thank you for your continued support.
I am challenging AI OCR using UiPath Document Understanding.
Here is the URL I referred to.
Trying Out UiPath Document Understanding

In the reference URL, Microsoft OCR was used, but I am using UiPath Document OCR.

However, after executing the validation station, when I click “Send”,
I get the message “An error occurred while saving data” and cannot proceed.

There is no error code in the message, and I do not understand which data is trying to be saved where, or what kind of error is occurring.
I am also exploring Document Understanding, and I am in a bit of trouble.

If anyone knows how to help, I would greatly appreciate your guidance.

Hello

What are the versions of each activity package? Aligning these to the latest version might resolve the issue.

Thank you for your reply. Here’s what it looks like:

I think this is the latest version, but… what do you think?

UiPath.IntelligentOCR.Activities 7.2.0-preview
UiPath.DocumentUnderstanding.OCR.Local.Server v2.0.0-preview

Hello

This applies to all activity packages in general, but unless there is a specific reason, I think it’s better to use the stable version rather than the preview version.

After changing all the packages to stable versions, the errors have disappeared!
UiPath.IntelligentOCR.Activities 7.2.0-preview → 6.27.3
UiPath.DocumentUnderstanding.OCR.Local.Server v2.0.0-preview → 1.5.1
UiPath.System.Activities 26.4.1 → 26.2.6

I was even able to write to Excel.
Thank you very much for your advice! I will be more careful regarding package versions in the future.
