We will need more of the error log than the last line. Please provide the full content of the error message. |

Use heroku logs to find out what the server log said when this happened.

Seems to be an error returning JSON: |

Yes, please share at least some of the app code, it is impossible to figure
this out like this. Be aware that this is not a support forum and this
issue might be closed since it is likely something wrong with your app.

Definitely looks like something is wrong with the app or the request. What does the endpoint code look like, and what's the request you're sending? |
|
Here's a snippet: |
|
If you look at the error you are getting in heroku the line that is failing is the last in this does not have anything to do with flask-restplus. This little snippet will also fail the same way Not sure what you are trying to do with that, but it looks like you are using requests to hit an invalid URL and then |
|
The URL is a placeholder for the one I'm using in the application, but thanks for pointing out the |
|
I have a similar problem, I am working with django. The app works fine locally but when I upload it on heroku I get the 500 error 2020-03-25T07:18:44.000000+00:00 app[api]: Build started by user [email protected] |
|
@toxicOxygen The same problem... did you solve it? |
|
@Ekzotika no I could not solve the problem |
|
I had to host the app on pythonanywhere, (it worked over there) |
|
My logs looks like this: Any idea on what could be the issue? |
|
i have the same problem too, i use flask-RESTfuly in combination with gunicorn, same settings as the op of the issue had. |
I don't know what I did but I made it to work. I started afresh deploy I think. |
|
I have the same problem. I use requests to parse the error and then use r.json() to parse the ouput. it works flawlessly in locally but gives a JSONDECODEDError when you deploy it. I dont know what to do. |
|
Has anyone been able to solve the issue? I ran into the same problem. |
|
I had this problem using rails and realized I had updated my schema locally but didn't run 'heroku run rails db:migrate'. Not sure what the equivalent is in Flask or Django |
|
that's caused due to bs4 scrapping issue don't know why sites are blocking heroku same code is working final on localhost but heroku is not able to scrap sites and is blocked so sites do not return much data and that's why we keep getting json decode error or if you try to run any query on bs4 coz you are using data which doesn't even exist on heroku . and yes that sucks |
|
I have the same problem! |
|
I figured it out! Thanks for the comments all! |
how |
|
I am new Heroku. After deployment, I run https://<app_name>.herokuapp.com/ got 500 internal server error. I cannot see any problem in log. Anybody can help me please |
|
Anyone solve this error? |

Same error at Node.js.. And nobody knows the solution.. |
|
Read the log. |
|
Same issue here: when the login is through the social platforms like google, I get 500. I removed the social and still get a HTTP/1.1" 302 error. Everything works perfectly on local. Even tested on Apache server , but fails on Heroku after deployed. Anyone has more info? |
and others
There doesn't seem to be any documentation on deploying to Heroku with flask-restplus. I've just deployed an app and am getting the following:
Error: INTERNAL SERVER ERROR.My Procfile is set to
web: gunicorn app:appand my app is set asapi = Api(app),app.wsgi_app = ProxyFix(app.wsgi_app), andapp = Flask(__name__), respectively. Anyone have any suggestions?The text was updated successfully, but these errors were encountered:
