TypeError: Cannot read property 'toString' of undefined

[shc261392]

Issue description

I encountered this error message when calling the store API:

{"message":"TypeError: Cannot read property 'toString' of undefined\n    at Object.proposeStorageDeal (/Users/james/numbers/starling-api/node_modules/filecoin-api-client/src/  cmd/client/propose-storage-deal.js:10:18)\n    at proposeDeal (/Users/james/numbers/starling-api/lib/apis/store/controller/store.js:115:51)\n    at ProposeDeals.Promise.all.   importedFiles.map.file (/Users/james/numbers/starling-api/lib/apis/store/controller/store.js:157:16)\n    at Array.map (<anonymous>)\n    at ProposeDeals (/Users/james/   numbers/starling-api/lib/apis/store/controller/store.js:154:21)\n    at store (/Users/james/numbers/starling-api/lib/apis/store/index.js:29:11)\n    at process._tickCallback   (internal/process/next_tick.js:68:7)","level":"error"}

After adding some debug console to the starling-api, I've found that the cid and name parameter passed to this function is always undefined if only 1 file is going to be stored.

It turns out that in this line

const FILE = filesCount === 1 ? file : file[0];

return proposeDeal(db, FILE, miners, i);

The FILE object is actually an array if there's only one file (the filesCount here is 1)

[ { cid: 'Qmf2WJRKky6WNnsmUs9pnQ39zufebJ6xusHYfbPS99yXjX',
fileSize: 13409,
name: 'xmp.txt' } ]

but the function proposeDeal should accept the file object instead of an array of the file objects

Steps to reproduce

The complete Python 3 code to invoke the API:

#!/usr/bin/env python3
 import json

 import requests

 base_url = 'http://localhost:3000'

 base_headers = {
     'Accept': 'application/vnd.starling+json; version=1.0',
 }

 def store():
     with open('xmp.json', 'r') as f:
         data = json.load(f)

     res = requests.post(
         url=base_url + '/api/store',
         headers=base_headers,
         data=data,
     )
     try:
         res.raise_for_status()
     except Exception as e:
         print(e.response)
     return res.text

 r = store()
 print(r)

xmp.json:

{
     "dataPath": "/Users/james/numbers/starling-test/xmp/"
 }

where the xmp/ folder contains only 1 file, an xmp.txt file

@finoradin Just to confirm, this bug with ProposeDeal is at the starling-api level and not go-filecoin? (cc @ognots)

I haven't tried to reproduce it, but based on how it has been reporting, yes that is my understanding.

@mishmosh @finoradin Thanks for the comments. According to current status, do you have any suggestion about using the store API?

This issue is expected to be fixed early next week, with the rewrite of the store command as part of the migration to lotus that @alexandrumatei36 is working on. I will update here once that's merged in.
