[BUG] Params named "default" get replaced with "_default", resulting in incompatible clients

Created by: seanlaff

Description

My api has a request object that contains a key called default, however when I generate client code from this spec, it gets converted to _default. Since my api expects default, the generated client code does not work.

I'm guessing this is escaping that happens in java since default is a java keyword. Is there any way around this?

Expected generated:

export interface RbacAddRoleRequest {
    default?: boolean;

Actual generated:

export interface RbacAddRoleRequest {
    _default?: boolean;
