completion fails, with unknown language id "tf" in the logs

I don't know all the implementation details of coc.nvim plugin myself but generally speaking the language server expects and supports two documented language IDs - terraform and terraform-vars. Language ID is usually implied from the file extension, but it is a different and not interchangeable concept, so if for any reason the editor ends up sending tf instead of terraform then that's a problem that will need rectifying there (on the editor/client side).

Before we start digging into the client code, can you share your configuration and/or confirm it matches https://github.com/hashicorp/terraform-ls/blob/main/docs/USAGE.md#cocnvim ?

Thanks!

As a side note NeoVIM 0.5.0+ has a builtin language client which may be easier to configure, see https://github.com/hashicorp/terraform-ls/blob/main/docs/USAGE.md#neovim-v050

[j3ffrw]

Thank you for the additional info about language id, I manage to fix it in vim by using

set ft=terraform

but ended up installing 'hashivim/vim-terraform' w/c does the above and a lot more. Works with 0.26.0 too.
