Hi @maximlamare,
This issue has been resolved some time ago. The current test pipeline fails on individual notebooks of Sentinelhub and OpenEO. Let me have a look.

There is currently a refactor going on of the SentinelHub samples, I asked William to take a look at the failing samples and implement a fix in the refactor. @Pratichhya Could you take a look at the OpenEO samples? Thank you!
