What

If you try to install the Python part of didcomm-demo following the instructions, it will crash with the following error:

ERROR: pydantic 1.10.2 has requirement typing-extensions>=4.1.0, but you'll have typing-extensions 3.10.0.2 which is incompatible.

Why

There are an error with typing-extensions version, for pydid and pydantic.
pydantic needs typing-extensions>=4.1.0
but
pydid needs typing-extensions<4.0.0,>=3.7.4
So, there are no combinations of typing-extensions that satisfies both libraries.

Success Criteria

• The instructions shall be ended successfully.

type: error
relatedto: installation issue

If a java client packs a message that includes a custom header, when it is unpacked by Python client, it fails with MalformedMessageCode.INVALID_PLAINTEXT error.

The other cases works fine: java-->java, python-->python, python-->java. All are unpacked without error.

How to reproduce the error:

• add .customHeader("return_route","all") in line 109 of DIDCommDemoHelper.kt

val message = Message.builder(
            id = UUID.randomUUID().toString(),
            body = mapOf("msg" to data),
            type = "my-protocol/1.0"
)
.customHeader("return_route","all")
.build()

• rebuild
• run demo.py
• check error at the end:
  Bob received MalformedMessageCode.INVALID_PLAINTEXT.

Same results were obtained using both libraries but outside this demo, just to confirm that is not a problem of the demo code. I'm opening the issue in this repo because I can't say if it's a problem in the python library or in the JVM library.
