I’m trying to change the custom field value with Node.js  
Here’s my code

client.tasks.update(‘1161678103000268’,{custom\_fields: {enum\_value : ‘725394518222140’{gid:‘725394518222142’}}})

What am I doing wrong?

Here is the correct synthax!

> The issue here is that you’re trying to update the definition of a custom field, not the value of a custom field on a task. The API call you want is something like PUT /tasks/\<task-id\> { "data": { "custom\_fields": { "1115652263994341": "10.5" } } }
