Bitbucket import error at the last hurdle

I have setup all the details in bitbucket and gitlab. I can see the list of bitbucket repo’s when I hit new project and select bitbucket. When I hit import I get this message

Access denied! Please verify you can add deploy keys to this repository.

I am an admin on the bit bucket account.

I am not sure what else to do. Please help.

Many thanks in advance
