I used ./dev.sh to run Baserow in dev mode but I got the following error.
what would be the reason?
Hello @abdolsattar, I’ll ask the development team to look into your request. In the meantime, please ensure that you have provided all necessary details as outlined in this template for submitting a new help topic: *READ ME FIRST* Technical Help FAQs - #2 by nigel. 
Hey @abdolsattar,
The first thing I can think of is the user running Baserow doesn’t have permission to create /baserow, If you are not in a container though that path is likely to cause issues as only the root user would be able to write there.
