ONLYOFFICE DocSpace released

An error has occurred while opening the file

When I used the spring example on the official website, an error occurred in opening the file:An error has occurred while opening the file

I hope to get some help, thank you.

Hello @caiwei

Do you mean this Java Spring example? If not please elaborate on how you access the application.

Yes, I used the java spring example on the website:

Did you configure it as per guide I’ve mentioned?
What installation type (Windows, Linux, Docker) did you use?

Yes, I have configured it according to the guide. I installed it on windows

Please provide a screenshot of the browser console when this error pops up.
Additionally, share Document Server logs that are located in C:\Program Files\ONLYOFFICE\DocumentServer\Log\ after reproducing the issue for analysis.

This is a screenshot of the browser:

There are two files in the document server log, the error.log is empty, and the contents of out.log are as follows:

I also found a warning in idea:

Did you try to create a file on the example page or did you try to upload your already existing file? If it was existing file, please specify its extension.

no, I run the java spring example of the official website

Please provide logs of Document Server. You can find them in C:\Program Files\ONLYOFFICE\DocumentServer\Log\ for Windows. You can archive them, upload to any cloud storage and send me a link to the archive (do it via PM in terms of safety).
Also, please provide \src\main\resources\application.properties config from Java Spring Example folder too.
