The reload tab has been failing to load since at least sometime last night (12+ hours). I've tried the "Clean app" option, but otherwise I'm not sure what to do. Here's the error that eventually comes back to the top of the screen:

This was caused by some un-optimised app server code on the Trigger.io side: your particular usage was especially awkward for our code hence the 504s.
I pushed a fix for it yesterday: everyone should see a snappier Reload tab now!

So I was trying to get Biograkn usecase for BLAST working , following the steps as per this video series. I was able to load the schema , but after that we need to execute python migrate.py to load data into it. I executed the command and i am getting the following error traceback
Traceback (most recent call last):

}
now this is not understandable why loading is not possible. Hence requesting for assistance.
There appears to already be a problem with the schema, since graql is trying to look for the label "database" but cannot find it.
You can check your schema using workbase:
1. connect to your local server (localhost:48555)
2. select your keyspace ("proteins")
3. click on the hierarchy symbol on the top left next to the grakn logo
If the schema is present, it will be visualized automatically.
I am using the SDK (Python) for Computer Vision published in Mocrosoft Docs (https://learn.microsoft.com/es-es/azure/cognitive-services/computer-vision/quickstarts-sdk/python-sdk).
When I run the code, this error occurs:
Traceback (most recent call last):

File "C:\Anaconda3\lib\site-packages\msrest\service_client.py", line 155, in format_url
base = self.config.base_url.format(**kwargs).rstrip('/')
KeyError: 'Endpoint'
I rather used the REST API method (https://learn.microsoft.com/en-us/azure/cognitive-services/computer-vision/quickstarts/python-disk)
However, it can be useful to complete the endpoint using this command line:
analyze_url = endpoint + "vision/v2.1/analyze"
Simply run the following command to reinstall customvision SDK worked for me.
pip uninstall azure-cognitiveservices-vision-customvision
pip install azure-cognitiveservices-vision-customvision
I'm running eventlet.monkey_patch() while trying to spin up a flask server which uses flask-socketio. This is the traceback:

Is there a fix for this?
My initial problem was that my server returns bad requests everytime I try to emit a message from the client. But, the other way works. Would really appreciate any kind of a solution. :)
So it looks like my install of apache airflow on a Google Compute Engine instance broke down. Everything was working great and then two days ago all the DAG runs show up stuck in a running state. I am using LocalExecutioner.
When I try to look at the log I get this error:
* Log file isn't local.
* Fetching here: http://:8793/log/collector/aa_main_combined_collector/2017-12-15T09:00:00
*** Failed to fetch log file from worker.
I didn't touch a setting anywhere. I looked through all the config files and I scanned the logs and I see this error

Any thoughts out there?
I solved this problem though in doing so I discovered another problem.
Long and short of it as soon as I manually started the scheduler, everything worked again. It appears the problem was that the scheduler did not get restarted correctly after a system reboot.
I have scheduler running through SystemD. The Webserver .service works fine. However I do notice that the scheduler .service continually restarts. It appears there is an issue there I need to resolve. This part of it is solved for now.
Look at the log URL, verify if it ends with a date with special characters +:
&execution_date=2018-02-23T08:00:00+00:00
This was fixed here.
You can replace the + for -, or replace all special characters, in my case:
&execution_date=2018-02-23T08%3A00%3A00%2B00%3A00
This happens here.
The FileTaskHandler can not load the log from local disk, and try to load from worker.
Another thing that could be causing this error is the exclusion of the airflow/logs folder or the sub folders inside it.
I am getting "Error handling request" and I can't really trace this down to a particular problem?
I am using gunicorn+nginx and my gunicorn setup is
gunicorn run:app -w 4 -b 0.0.0.0:8080 --workers=1 --timeout=300
here is the error message

can anybody give me a hint how to debug this? I don't have much experience with server usage...
thanks

tl;dr: This isn't an issue with gunicorn or nginx. Your view function in your Flask app is not returning a response. Check the return statement in your view function for whatever route you are accessing when you get this error.
Beginning at the Line
Traceback (most recent call last):
You can see the stack trace produced by the python interpreter. The stack trace shows the sequence of nested functions leading up to the point where your code failed. In my limited experience, the python interpreter stack trace has reliably directed me to the fault in my code.
In your case here, the final line:
ValueError: View function did not return a response
provides some more detail about the error and should give you pretty good idea of what went wrong (Your view function didn't return a response).
The next line up from the bottom will show you the function that triggered the error, and its exact location in your code:
File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 1566, in make_response
raise ValueError('View function did not return a response')
In this case the error is raised by a function in the flask source, so unless you edited that, that is probably not where you need to make a fix. Based on the specific ValueError at the end of the trace, I'd go straight to my views function. In Flask that probably looks something like this (example from Flask tutorial):
#app.route('/')
def show_entries():
cur = g.db.execute('select title, text from entries order by id desc')
entries = [dict(title=row[0], text=row[1]) for row in cur.fetchall()]
return render_template('show_entries.html', entries=entries)
That last line seems like a good place to start in your case, since the error says nothing is being returned.
