cannot send request with form-data body

[karnadixyz]

Hi, i try to send request data with:

• raw body (json) => OK
• header => OK
• form-data body => failed

my error is:
com.fasterxml.jackson.core.JsonParseException: Unexpected character ('-' (code 45)) in numeric value: expected digit (0-9) to follow minus sign, for valid numeric value at [Source: java.io.ByteArrayInputStream@1a85e949; line: 1, column: 3]

my camel route:
.post("/formdata") .consumes("application/json") .param() .name("name") .type(RestParamType.formData) .endParam() .to("bean:myFunction?method=dataNIBFormData")

do u have solution?
thanks
