(English is not my native language)
It is a start use about Ryven, I just do pip install ryven and run ryven as the document say:
https://ryven.org/guide#/?id=flows
The version of python is 3.10.1 on linux.Version of ryven is 3.1.0.
When I click the button: CREATE NEW PROJECT.Error comes(just on linux,not come on windows):
Traceback (most recent call last):

cls.identifier = prefix + cls.identifier
TypeError: can only concatenate str (not "NoneType") to str
The error comes from file Node.py,source code below:
@classmethod
def build_identifier(cls):
"""
sets the identifier to class name if it's not set, and adds the identifier prefix
"""
prefix = ''
if cls.identifier_prefix is not None:
prefix = cls.identifier_prefix + '.'
if cls.identifier is None:
cls.identifier = cls.__name__
cls.identifier = prefix + cls.identifier
# notice that we do not touch the identifier compatibility fields
Finally get by doing debug:
If the cls.identifier is None,the codes's logic is to set the cls's attribute identifier as cls's __name__: identifier also be None after the code cls.identifier = cls.__name__.
Why?I do the codes to test:
class A():
identiry: str = None
if __name__ == '__main__':
cls = A
if cls.identiry is None:
cls.identiry = "hello"
print(cls.identiry)
Comes out:
>>>hello
Why not successful just when setting attribute in Ryven?
