undefined symbol: FIPS_mode

[CX-ZG]

My lua-resty-openidc encountered an error while running. I haven't solved it yet：

@CX-ZG most likely difference in OpenSSL version (are you on 1.1.x?). Which version are you running?

Perhaps we need to pcall this and default to false in case it fails.

In the openssl-1.1.1w version, I encountered the same error. When I used local status, res = pcall(require("resty.openssl").get_fips_mode()), I got the same error. Later, I commented out the line IS_FIPS = require "resty.session.utils".is_fips_mode() in utils.lua and changed it to IS_FIPS = false, which resolved the issue. However, I'm not sure if this modification affects the overall functionality.
