SAP BTP: Error activating BAS extensions

GiuliaTurani — Wed, 22 Jul 2026 15:03:17 GMT

Hi everyone,

opening my dev space in BAS I get the following error and some core extensions, such as the SAP HANA Database Explorer, are no longer working

I tried recreating the dev space without success. The error persists in the new dev space, and I cannot even clone projects from Git.

I have attached the error log for reference

Hi,
Can you please mention on which BTP region you have BAS subscription where you encountered the issue?
Do you still encounter the issue?
Thanks, Rotem
