Does anyone have or had the same problem by any chance?
When we try to export e.g. a collection of objects as XLSX (e.g. for batch update of the objects), the export fails as long as images are embedded in text fields. Removing the images solves the problem.
According to the documentation it should work, but it does not work for us.
Please report bugs like that to our support desk: openbis-support@id.ethz.ch.
Your fastest way to get a solution to a problem with such a kind of error is to copy/paste the complete error in a text file and send it to the Helpdesk. The part that you did show is not sufficient.
You might also want to report your browser and a screenshot of the settings page you used for the export.
The export and import have been tested exporting/importing complete spaces from real users, apart from all the development tests. Even if so is a complex feature, and you might be using the system in some particular way that triggers this that was not tested before.
