Cannot run locally

[YourHarbour]

Hi, I tried as the README that deploys on Heroku, which successes in response to the URL, however when I tried to run locally with command

node web.js

The same URL will always show errors about the phrase of the JSON file.

SyntaxError: Unexpected end of JSON input at JSON.parse (<anonymous>) at _processStopped (/Users/harbour/Desktop/graph_planner/cloud-solver/web.js:190:23) at ChildProcess.exithandler (child_process.js:397:5) at ChildProcess.emit (events.js:400:28) at maybeClose (internal/child_process.js:1055:16) at Socket.<anonymous> (internal/child_process.js:441:11) at Socket.emit (events.js:400:28) at Pipe.<anonymous> (net.js:675:12)

The URL is
http://127.0.0.1:5001/solve?domain=http://www.haz.ca/planning-domains/classical/blocks/domain.pddl&problem=http://www.haz.ca/planning-domains/classical/blocks/probBLOCKS-4-1.pddl
and

Any help?

Kind of a shot in the dark, but it may be a node versioning issue? The heroku stack of stuff used for this (found here) is quite dated.

If you're willing to shrug it off for now, there is a new project meant to replace this one entirely that we're putting the final touches on: https://github.com/AI-Planning/planning-as-a-service
