Issue Setting Custom Field in ClickUp

Describe the problem/error/question

Hi to all,

I am running into a problem when using the “Set Custom Fields” node in ClickUp. I need to insert a numeric value (the ID of the bound folder) into a custom field of type Text.

Error description:

When I try to insert a numeric value, I get an error

Tried adding toString() to the value but the result is the same.

Interestingly, when I write just numbers in this field, I get the same error. However, if you add at least one character (such as comma, quotation mark, etc.), the value is passed successfully.

Obviously, I need to convert the numeric value to a String somehow, but I can’t find the right approach.

Additionally:

When I change the type of the custom field to Number, the value is passed, but in a dotted format (eg “901.213.664.19”), which also doesn’t work.

Any advice and solutions would be greatly appreciated!

Thank you!

What is the error message (if any)?
