A JSON text must at least contain two octets!

[ddavtian]

I think this might be an issue in the JSON parser?

this is a server error from parse as per the 502 response code. it was retried so hopefully it succeeded? in any case this isn't a client bug

[henrik]

"A JSON text must at least contain two octets!" is tech talk for "The JSON library got an empty string but expected some JSON, at the very least an {}".

It might be helpful if the client would encapsulate this and instead raise an error something like Parse::ServerError.

I'm fine with this. Wanna send a PR?

[ericcj]

this one is actually logging of a retry, but it would be indeed be re-raised as JSON::ParserError if retries were exhausted. it would probably be preferable to encapsulate all server errors (5xx, timeout, patron, whatever) under Parse::ServerError as long as it captured the cause

[henrik]

I'm afraid I don't have the time to make a pull request at the moment. Possibly later, if we do a "handle Parse errors gracefully" sprint.

Hello,

I have the same issue as you had. Here is the code base I am running on.

params = {:first_name => "John", :last_name => "Smith"}

uri = URI.parse(make_uri("person/" + id.to_s)) Net::HTTP.start(uri.host, uri.port, :use_ssl => uri.scheme == 'https', :verify_mode => OpenSSL::SSL::VERIFY_NONE) do |http|

request = Net::HTTP::Patch.new(uri.request_uri)
request.add_field('Content-Type', 'application/json')
request.body = JSON.dump(params)

@response = http.request request # Net::HTTPResponse object

end

JSON.parse @response.body

I hope you would like to help me with any solution.

Best regards,

John
