StreamableHTTPServerTransport module not found when running example server

[andrewdwooten]

Describe the bug
A clear and concise description of what the bug is.
I'm attempting to implement one of the server examples: jsonResponseStreamableHttp. I've copied the server into my project, but whenever I attempt to start the server I get an ERR_MODULE_NOT_FOUND looking for StreamableHTTPServerTransport in streamableHttp.js. I'm currently working with version 1.9.0. I had a look into the contents of the package in my node_modules folder, but wasn't able to find a reference to jsonResponseStreamableHttp.

To Reproduce
Steps to reproduce the behavior:

1. Copy file contents locally
2. Attempt to start server with node filename
3. See error

Expected behavior
A clear and concise description of what you expected to happen.
I expected the server to start up and print its logging statements into the terminal.

@andrewdwooten, are you running form checked out fork of SDK or as a package? if a package, which version do you use?

[wong2]

You should use v1.10

[andrewdwooten]

@ihrpr I was using it as a package, v.1.9.0. The update to v1.10 has me up and running. Thanks so much for y'alls help!
