Avoid percent-encoding for "(" and ")" characters.#9
Merged
Conversation
The VRChat API does not accept percent-encoded variants of InstanceID, specifically the characters "(" and ")". This causes an error when attempting the following API call:
```
https://api.vrchat.cloud/api/1/instances/wrld_28aab3e4-953f-4c85-9223-ef29a0873a6e:31124%7Egroup%28grp_b2a19685-c53e-4c5a-9503-744a5373bf2c%29%7EgroupAccessType%28plus%29%7Eregion%28use%29/shortName
```
```json
{"error":{"message":"\"malformed url\"","status_code":400,"waf_code":26497}}
```
When using the raw string without encoding, the API yields a `200` response as expected.
```
