Buffer is not 'modifiable'

[mradspieler]

After upgrading to nvim 0.10 I get an error, that the buffer is not modifiable
nvim: 0.10
OS: linux

:SqlsSwitchConnection
:SqlsShowTables

Error executing vim.schedule lua callback: ...s/.local/share/nvim/lazy/sqls.nvim/lua/sqls/commands.lua:32: Buffer is not 'modifiable'
stack traceback:
        [C]: in function 'nvim_buf_set_lines'
        ...s/.local/share/nvim/lazy/sqls.nvim/lua/sqls/commands.lua:32: in function 'handler'
        /usr/share/nvim/runtime/lua/vim/lsp/client.lua:687: in function ''
        vim/_editor.lua: in function <vim/_editor.lua:0>

any hints?
