Sending query parameter in int array instead of string

[shu-bc]

After updating activegraph from v10.0.1 to v11.4.0 and neo4j-ruby-driver to v4.4.5., authentication logic in my application stops working because it cannot find data from Neo4j database, which is running in docker using image neo4j:4.0.10-enterprise.

Authentication code looks like this:

authentication_token = headers[token_param_name]
User.find_by(authentication_token: authentication_token)

In query log, I found authentication_token parameter is strangely int array not string.

2024-06-22 03:27:57.371+0000 INFO  0 ms: bolt-session   bolt    neo4j-ruby/4.4.5                client/172.19.0.5:54638 server/172.19.0.3:7687> neo4j -  - MATCH (n:`User`) WHERE (n.authentication_token = $n_authentication_token) RETURN n LIMIT $limit_1 - {n_authentication_token: [111, 83, 80, 74, 89, 72, 111, 103, 49, 80, 70, 85, 117, 121, 107, 45, 51, 107, 74, 98, 65, 81], limit_1: 1} - {}

Hard coding token, or sending token by query string work perfectly well.

User.find_by(authentication_token: 'tokenhere')
User.find_by(authentication_token: params[:token])

I tried to create new instance of the string by dup, clone, String.new, they all failed.

authentication_token = headers[token_param_name].dup
authentication_token = headers[token_param_name].clone
authentication_token = String.new(headers[token_param_name])

But creating new string by concat each char of the original string works.

    authentication_token = ''.dup
    headers[token_param_name].each_char do |char|
      authentication_token << char
    end

I am sure that activegraph gem is not the cause, since sending query directly using this exmple code reproduces the same problem.
