Switch tmux windows using :Telescope tmux windows not working

[amrit073]

I have two tmux windows, both with neovim.
When I do :Telescope tmux windows, it pops up the my windows, when I select the window i want to switch to, The error I see is:

E5108: Error executing lua: vim/_editor.lua:0: nvim_exec2(): Vim(!):E499: Empty file name for '%' or '#', only works with ":p:h": silent !tmux switchc -t "#:@2" -c "/dev/pts/0"
stack traceback:
        [C]: in function 'nvim_exec2'
        vim/_editor.lua: in function 'cmd'

I installed the plugin using packer:

  use 'camgraff/telescope-tmux.nvim'

And loaded the extension to telescope:

pcall(require('telescope').load_extension, 'tmux')
