Error 10: Field Must Be Numeric

PayMe's message with language: "en": Field must be numeric

A field that must be a number isn't. status_additional_info holds the value, not the field name.

Usual causes

• installments that isn't a number: the sandbox answered HTTP 500 for x.

What to do

• Send a number, or a string of digits such as "1". Check the field on its reference page.
