Deepstream_server add failed using add interface /api/v1/stream/add

[Captian]

I had problems with both modes when using the test program, as described below
1：Use the default mode nvmultiurisrcbin
1）：Configuring environment variables export NVDS_SERVER_APP_PERF_MODE=1 ，
2）：Use the default mode nvmultiurisrcbin ， within_multiurisrcbin: 1
3）：After the test program is started, the test program outputs the received
message using the added media stream interface in the readme file, but the return fails
Please see screenshot p1

2：Use REST server with the application
1）：Configuring environment variables export NVDS_SERVER_APP_PERF_MODE=1
2）：within_multiurisrcbin: 0
3）：The test program failed when it ran into the function that loaded the stream from the configuration file
Please see screenshot p2

Seems you are testing DeepStream REST API server in: DeepStream With REST API Sever — DeepStream documentation 6.4 documentation
Which DeepStream version are you used?

Hello, I am using DeepStream-6.4. This problem should be caused by nvurlsrcbin not being installed correctly. I re-ran the install.sh in the deepstream directory and solved it
