Unable to use qt-mountainview about mountainlab-js

[theilmbh]

Hi all,
We had a similar error on a fresh install of mountainlab. We found that the sumit.json and process_cache.json in ~/.mountainlab/database were completely empty on a fresh install, and this seemed to be the cause of the problem. We simply added [] to these empty files and then things would run. I just wanted to bring this to your attention in case anyone else runs in to similar problems.

Hi there! Could you please post the output for ml-prv-locate raw.mda.prv? If it finds a file it would be work to check that file exists.

I think there may be a bug here as well but it could be a day or two before someone has a chance to fix.

@magland I haven't looked into this yet but it seems prv_create is failing silently and returning undefined instead of an error.

(node:17436) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'original_checksum' of undefined

I tried with

ml-prv-locate raw.mda.prv

And it returned with the correct location of my data:

/media/user/DATA/Projects/eeyd_a5GABA_Project/EE11_FF+_Experiment/EE11/01_20180604/EE11_01_20180604.mda/EE11_01_20180604.nt1.mda

Thanks ... could you also post the exact command you tried with ml-prv-create?

[yukidai]

Yes, its just:

(mlab) user:EE11_01_20180604.nt1.mountain$ ml-prv-create pre.mda

Weird! OK thanks I will try and look into this properly this week.
