[Performance degradation] Kintone REST API degradation after the June update

(Updated: 11th June 2019) This issue has now been resolved:




After the maintenance on Friday, June 7, we noticed a performance degradation in the Kintone REST API.

Error details

Kintone REST APIs return errors when all of the following conditions are met:

  • a request parameter is included that can be specified by either an Integer or a String
  • the above request parameter is specified as a string
  • the above request parameter is a number starting with a 0

Sample request resulting in an error

The sample below includes a 0 at the beginning of the id parameter, which results in an error:

var body = { "app":"2303","id" : "09"};
kintone.api(kintone.api.url('/k/v1/record', true), 'GET', body);

Reasons for the Error

The maintenance included a library version update that caused numbers specified as strings and starting with a 0 to be recognized differently than usual, causing an error.

How to avoid the errors

Remove the 0 from the beginning of the string, and then specify it in the parameter:

var body = { "app":"2303","id" : "9"};
kintone.api(kintone.api.url('/k/v1/record', true), 'GET', body);

Update plans

We are currently working on fixing this issue, and will post a new notice when the fix has been applied.
