How do I handle a colon in the url? 

I have an http path like this
"/v1/{walletName}:generateAddress": 

The :generateAddress is becoming a string parameter from the generated client.

`
const response = await client.walletServiceGenerateAddress(name, ':generateAddress', {
    network: networkName,
 });
`

Is there a way to escape the colon in the path? or an generate parameter to ignore colon based http path variables?
