higlass-manage start raises error ValueError: invalid literal for int() with base 16: b''

[enjras]

I just installed higlass, but if I try to start working with it by typing higlass-manage start, the following error is raised:

`Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/urllib3/response.py", line 697, in _update_chunk_length
self.chunk_left = int(line, 16)
ValueError: invalid literal for int() with base 16: b''

During handling of the above exception, another exception occurred:

I obtain similar problems by trying to ingest a bedfile.

Any help is very much appreciated!

Hi! Could you take a look at the solution here and see if it helps?

higlass/higlass-manage#67

[enjras]

I'm not so sure, in that solution, you suggested to go to the application settings, clear the cookies and reinstall urllib3. I apologize if the question is stupid, but it is not clear to me which application you are referring to.

[pkerpedjiev]

Oh, I'm sorry. You don't have to reinstall urllib3. Just go to your browser's developer tools.

Go to application:

And then under cookies remove the one for localhost (not shown in the screenshot but it should be there for you):

I think I solved the problem by modyifing the file response.py as you suggested. I was able to find it at the path: /Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/urllib3/response.py

Thank you so much!

btw if I went through the developer tools (thanks for explaining there weren't cookies for the localhost)
