Chalice: KeyError on variable assignment?

[daynebatten]

So, I have code like this...

~~~
@app.route('/auto_thing', methods=['POST'], cors=True)
def index():
#Stuff happens in here

@app.route('/full_thing', methods=['POST'], cors=True)
def index():
stuff = 123
~~~

When I run chalice deploy I get a KeyError: 'stuff'. There is literally nothing else in the function for the full_thing endpoint at this point.

What in the world is going on here? How do I fix this so I can deploy?

Full stack trace:

Issue was apparently that functions for both endpoints had the same name. Didn't realize this wasn't acceptable, though it should have been obvious.

I'd recommend a more sane error message when this occurs...

[stealthycoin]

What version of chalice are you using? I believe that the error reporting logic was updated to include more information other than just the str() of the exception.

@stealthycoin same issue!

[thebenwaters]

I'm using chalice 1.6.0 with typing 3.6.4

[thebenwaters]

Also literally same problem!

[danlaudk]

same stack trace, and chalice version, python3.6 . Now i receive the same error when I seem to be using some protected word "top" as my route method.

@app.route('/top_thing', methods=['GET'])
def top():
  # do stuff

This was a weird error report for an already weird error

[freaker2k7]

Same issue!!!

In my case .chalice/config.json was not well formatted.

[prabhukumaar]

Had the same issue, fixed once after defining different function names for second endpoint. such as def index, def index2

@app.route('/auto_thing', methods=['POST'], cors=True)
def index():
#Stuff happens in here

@app.route('/full_thing', methods=['POST'], cors=True)
def index2():
stuff = 123
