Heroku Deploy gives Template does Not Exist Error, but the Template worked fine on my Local Server about slackin HOT 9 OPEN

I'm trying to deploy an app to heroku for the first time following the tutorial by Corey Shaeffer. After allowing the correct host, I tried heroku open again in the command line and got an error message saying: " TemplateDoesNotExist at /
blog/home.html, blog/post_list.html "

However those templates do exist and worked in development. No idea what is going on, super new to this. Does anyone know what could be up?

@dwfinley , did it work for you?
I just tried and seeing below error in Heroku web logs:

hi, i am facing the similar issue as mentioned above. May i know what is the solution for that?

I finally figure it out. In my case, the letter 't' for 'templates' need to be capitalised.
'DIRS': [os.path.join(BASE_DIR, 'Templates')],

edit: if you are using Flask...

app = Flask(__name__, template_folder='working-templates-folder/')

add the template_folder argument above to have the app look into your 'blog' folder...

app = Flask(__name__, template_folder='blog/'

I was getting the same "jinja2.exceptions.TemplateNotFound: index.html" error raised from the flask/templating.py module, before I found this fix...

also, you can set the "EXPLAIN_TEMPLATE_LOADING" variable in both my development and staging configs (in config.py file) to 'True' like this:

class StagingConfig(Config):
    DEVELOPMENT = True
    DEBUG = True
    ENV = "Staging"
    EXPLAIN_TEMPLATE_LOADING = True

class DevelopmentConfig(Config):
    DEVELOPMENT = True
    DEBUG = True
    ENV = "Development"
    EXPLAIN_TEMPLATE_LOADING = True

to see more debug output of where the app is looking for your template files...

so is there a solution?
