error loading prompt... is the backend running?

[adocampo]

I've just installed MRS on Linux with docker. So far it builds everything and I have two new containers:

2e6659281247        mimic-recording-studio_backend    "sh start_prod.sh"       13 minutes ago      Up 8 minutes            0.0.0.0:5000->5000/tcp                                                                                 mrs-backend
01cbe2225d95        mimic-recording-studio_frontend   "bash start.sh"          13 minutes ago      Up 8 minutes            0.0.0.0:3000->3000/tcp                                                                                 mrs-frontend

My docker instances are on a NAS server (192.168.1.100) and I'm accessing it with my network computers (192.168.1.0/24). My mrs-backend IP is 172.21.0.2/16 while the mrs-frontend is 172.21.0.3/16. I can ping between them through IP and hostname as expected.
I can also telnet to ports 5000 and 3000 of my docker host from my network computers.

So far, I can connect to the frontend just fine. But when I go to start recording, a error loading prompt... is the backend running? message appears on the screen

On the /src/prompts/ I have both the english_corpus.csv and english_corpus_no_dups.csv files.

So, I'm a bit lost, becasue logs shows no errors

Make sure you have set the corpus path in docker-compose.yml.
Also I assume you have tried using 'english_corpus_no_dups.csv', it has an empty line because of which you have that error. Pull the latest code and give it a shot. Let us know if you still have any issue.

I got a similar error on windows. the batch script is broken, had to fix many things to make it work. But a major error was UnicodeDecodeError: 'charmap' codec can't decode byte 0x99 in position 1683: character maps to <undefined> which I narrowed down to the corpus file not being read at utf-8, changing line 80 in file_system.py to with open(prompts_path, 'r', encoding="utf8") as f: include utf-8 fixed the problem of the backend not starting

I had the same issue when accessing not by localhost url.
Try the following on your local computer.

autossh -L 3000:localhost:3000 DestinationIPFrontend
autossh -L 5000:localhost:5000 DestinationIPBackend

Then recording with http://localhost:3000 in your local browser should work.
Thanks to mycroft community member @gras64 for this tip.

check index.js file in api folder in frontend. in there apiRoot is mentioned as localhost change the localhost to your backend running IP.

I am assuming this code has never been fixed because a) this ticket is still open and b) I just got this error in 2023. Feels like this product needs some love if even the prebuilt dockers don't work properly. Seems to be a lot of bugs which have simple (for a developer) fixes.
