@hrsh7th Alas, this is still happening to me :(

When you configure cmp, check whether you have used the wrong configuration.

cmp.setup({
    completion = {
        completeopt = 'menu,menuone,noinsert',
        autocomplete = true,
    },
...

Here, autocomplete is configured as bool type. But according to the error message, it should be of type table.

if vim.tbl_contains(config.get().completion.autocomplete or {}, trigger_event) then

[tzachar]

Not related, this is my config:

autocomplete = { types.cmp.TriggerEvent.InsertEnter, types.cmp.TriggerEvent.TextChanged },

For me, the error only showed while editing ts, tsx filetypes. And I could solve the problem by removing this line.

["textDocument/publishDiagnostics"] = vim.lsp.with(vim.lsp.diagnostic.on_publish_diagnostics),

[arjablc]

My fix I had a typo where I forgot parenthesis

local capabilities = require('cmp_nvim_lsp').default_capabilities()

and passed in capabilites when calling the

lspconfig.[lsp_server].setup({
  capabilities = capabilities
})

after adding the parenthesis I no longer get the error. this error occurs when passing something to the setup function that is not a table. so i think recheck that
