When I try to create a Contact, with a linked Account that has Account_Name formed of digits, i.e. "778" I receive the following status code: 202. Error message "You do not have sufficient authorization to associate this record. Contact the administrator."
exception code: INVALID_DATA
error details: {"api_name"=>"Account_Name"}

According to this issue
https://help.zoho.com/portal/community/topic/zoho-crm-api-v2-invalid-query-formed-error
It is necessary to escape special characters in the query (e.g. brackets).

I feel that this should be done at the API level
Here is some code that fails

    module_instance =
      ZCRMSDK::Operations::ZCRMModule.get_instance('accounts')
    crm_data =
        criteria = "(Account_Name:equals:Acme (Co.))"
        api_res = module_instance.search_records_by_criteria(criteria)
        api_res.data[0]
      end

What the hell is going on with gem's code? Guys are you serious? How "this" became published? 32к additions, no code style, 6000 lines of code in every next file. What is it? Why did you publish it?

I use Exception Notifier gem, which includes the Exception message attribute in the notification.

SDK populates a few attributes in the exception, but not the message, which means we lose valuable insight into the root cause of the message.

The library is using an older version of the json gem.
The newer version has some useful features (e.g. parsing a single value (not an object) correctly)
json 2.2.0

JSON.parse("\"hello\"")
 => "hello" 

json 1.8.6

JSON.parse("\"hello\"")
Traceback (most recent call last):
        1: from (irb):1
JSON::ParserError (784: unexpected token at '"hello"')

When using file persistence I encounter an error when refreshing tokens:
Encoding::UndefinedConversionError ("\xBE" from ASCII-8BIT to UTF-8)

I found that the file where the tokens are persisted has encoding of ASCII-8BIT but my encironvoment is using UTF-8
