attempt to index local 'self' (a number value)

[swtch1]

Description

I updated to the latest version of nvim-lspconfig. Now when starting neovim I get the following error.

Here's the relevant snippet from my config

local lsp_installer = require("nvim-lsp-installer")
local cmp_lsp = require('cmp_nvim_lsp')
local lsp_installer_servers = require('nvim-lsp-installer.servers')
local requestedLSPServers = {
    bashls = {},
}
for lsp, opts in pairs(requestedLSPServers) do
    local capabilities = cmp_lsp.default_capabilities(vim.lsp.protocol.make_client_capabilities())
    local available, lsp_server = lsp_installer_servers.get_server(lsp)
    opts["on_attach"] = on_attach
    opts["capabilities"] = capabilities
    opts["flags"] = { debounce_text_changes = 150 }
    if available and not lsp_server:is_installed() then
        lsp_server:install()
    end
    lsp_server:on_ready(function()
        lsp_server:setup(opts)
    end)
end

Steps to reproduce

Apologies but I'm not good enough to create a minimal working config in the amount of time I have. I have added the relevant parts of my config below.

Actual behavior

Error detected while processing /Users/<me>/.config/nvim/init.vim:

Expected behavior

No error

Minimal config

This is the relevant snippet from my config.  Notice I'm using `nvim-lsp-installer`.

local lsp_installer = require("nvim-lsp-installer")
local cmp_lsp = require('cmp_nvim_lsp')
local lsp_installer_servers = require('nvim-lsp-installer.servers')
local requestedLSPServers = {
    bashls = {},
}
for lsp, opts in pairs(requestedLSPServers) do
    local capabilities = cmp_lsp.default_capabilities(vim.lsp.protocol.make_client_capabilities())
    local available, lsp_server = lsp_installer_servers.get_server(lsp)
    opts["on_attach"] = on_attach
    opts["capabilities"] = capabilities
    opts["flags"] = { debounce_text_changes = 150 }
    if available and not lsp_server:is_installed() then
        lsp_server:install()
    end
    lsp_server:on_ready(function()
        lsp_server:setup(opts)
    end)
end

Hi, I am also receiving the error. Just updated my nvim-lsp-installer last night.
