URI encryption doesn't work

[shaghayegh9574]

I'm using nginx-secure-token-module for uri encryption.
I want to encrypt my uri from root so add the bellow configuration to location "/":
location /
{

	proxy_pass http://192.168.252.3:80;
	proxy_set_header Host	$host;
	secure_token_encrypt_uri on;
	secure_token_encrypt_uri_key 000102030405060708090a0b0c0d0e0f101112131415161718191a1b1c1d1e1f;
	secure_token_encrypt_uri_iv 00000000000000000000000000000000;
	secure_token_types text/html;
			
}

but when open my site,by clicking on any uri got response 400 and on got the bellow error on nginx error log :
ngx_http_secure_token_decrypt_uri: ngx_decode_base64url failed -1, client: 192.168.0.100, server: example.com, request: "GET /tmp/ HTTP/1.1", host: "example.com"

same issue here, want to use this with minio
