Query string value "=" is encoded in playlist

Wowza Streaming Engine

Hi.

I want to link Wowza server with Google Cloud CDN.

I’m going to add access control using Cloud CDN’s Signed URL.

Signed URLs are created with Base64 URL Safe Encoding.

“=” is encoded in my wowza Server Playlist.

= --> %3D

EX)
http://3.138.191.8:1935/test/mp4:sample.mp4/playlist.m3u8?URLPrefix=aHR0cDovLzMuMTM4LjE5MS44OjE5MzUvdGVzdC8=&Expires=1664271224&KeyName=abcd&Signature=JgOJKNDRHkIlL8u42pAOM6AbxFg=

#EXT-X-VERSION:3

#EXT-X-STREAM-INF:BANDWIDTH=868638,CODECS=“avc1.42c015,mp4a.40.2”,RESOLUTION=512x288

chunklist.m3u8?URLPrefix=aHR0cDovLzMuMTM4LjE5MS44OjE5MzUvdGVzdC8%3D&Expires=1664271224&KeyName=abcd&Signature=JgOJKNDRHkIlL8u42pAOM6AbxFg%3D

So the request keeps failing.

Is there no way?
