response is not formatting json

[garrettkrohn]

First off, thank you so much for reviving this project, very excited for it!

I followed the installation instructions, trying both luarocks and lazyvim, but the json responses won't format.

Here are the logs:

I've done as much digging as I can and it seems to be this line: Error while parsing verbose curl output. The odd thing is it prints a blank line, so maybe a blank line is breaking it? Trying to learn more about neovim plugins, but definitely out of my element. Thank you!

The error log isn’t related to formatting. Do you have formatexpr or formatprg set for json filetype? That might be the issue here.
rest.nvim uses native gq command for formatting. If you don’t set formatexpr or formatprg option for json filetype, gq command won’t be able to format response body properly.
Try open json file and type gggqG. If that doesn’t work that means you don’t have any formatter attached to json filetype.
Comment I wrote in other issue might help.

I should add this check to checkhealth command.

I have formatexpr already set but not formatprg.
Formatting was fixed for me when I added the following in my config:

vim.api.nvim_create_autocmd("FileType",  {
      pattern = { "json" },
      callback = function()
        vim.api.nvim_set_option_value("formatprg", "jq", { scope = 'local' })
      end,
})

But ofcourse I already have jq installed.

[boltlessengineer]

@chardskarth what formatexpr did you set?
v:lua.vim.lsp.formatexpr() won’t work.

See this issue: #414 (comment)

Edit: reference

[boltlessengineer]

Closing the issue as this seems to be mainly a vim.lsp.formatexpr() issue.
If formatting still doesn’t work, please create a new issue with reproducible steps.

Thanks @boltlessengineer thanks for picking this project up!

Thanks!! I was struggling trying to set the formatting and this config made it work!
