graphite error "'ParseResults' object has no attribute 'raw'" when call /render

+1 Got the same exact error today on a new Graphite installation ... otherwise exploring the metrics and retrieving data seem to be working properly.

AttributeError: 'ParseResults' object has no attribute 'raw'

UPDATE: reinstalling pyparsing with version 2.4.7 (the one I have in another working environment) instead of 3.0.4 (the one presenting the error) seems to solve the problem.

I encountered this today as well. Graphite was displaying standard data just fine but I couldn't run any functions against the data (averageSeries, sumSeries, etc). These requests would all result in an error 500 in the browser with the same stack you've posted above. The release notes for pyparsing==3.0.4 describe this as intended behavior:

result = Word(alphas).parseString("abc") result.xyz = 100

now raises this Python exception:

AttributeError: 'ParseResults' object has no attribute 'xyz'

To add new attribute values to ParseResults object in 3.0.0 and later, you must assign them using indexed notation:

result["xyz"] = 100

And if you check the referenced line in your stack (grammar_unsafe.py line 83) you'll see that Graphite is indeed attempting to assign the 'raw' attribute without using the indexed notation. I attempted to edit this line with varying results. Some graphs would render but there were other issues with apache restart, so simply updating the notation used in setting toks[0].raw only complicates the issue. I've logged an issue with graphite-web and in the interim, have downgraded my pyparsing to 2.4.7 as suggested in the recommended answer.
