absolute beginner here having an absolute nightmare deploying a tiny website to Heroku. I have worked through numerous issues to get to this point, but I now seem to have hit another wall. I have raised this as a support ticket with Heroku, but unless it is an issue on their side I doubt whether they will come back to me with a clear answer.
I can successfully deploy to Heroku, however, when opening up my web app I can only see the words "Internal Server Error" in place of my site. I receive an issue/error through to my Sentry log, which is as follows:
MESSAGE

I have used django-cookiecuttter as the base template for my site. Only yesterday I read a separate issue raised against django-cookiecutter for another Internal Server Error issue which I hoped may help me too (even though the details appeared different), but I have tried removal of "min" from the css file without success.
As the error message mentions storage and compressor, is it possible that this is Django-compressor related or whitenoise (I have both installed)? I have looked into trying to compile offline looking the instructions here, but this might be out of date by now and as my site is working well locally I want to avoid unnecessary coding if I can help it. Assistance would be greatly appreciated.
I am using windows with Python 3.6.2 and Django 2.0.2. My production static settings are as follows:
# Static Assets
# ------------------------
STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'
# COMPRESSOR
# ------------------------------------------------------------------------------
COMPRESS_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage'
COMPRESS_URL = STATIC_URL
COMPRESS_ENABLED = env.bool('COMPRESS_ENABLED', default=True)
Thanks in advance.
UPDATE:
I still see the Internal Server Error, however, I'm sure this relates to the way I have set up my bucket. I have followed this tutorial adding the IAM group and policy, but I must be doing something wrong because I get an improperly configured error message with the following details:
Client error:An error occurred (403) when calling the HeadBucket operation: Forbidden
My policy in AWS is as follows (of which I have tried a few iterations of):
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "VisualEditor0",
"Effect": "Allow",
"Action": [
"s3:ListAllMyBuckets",
"s3:HeadBucket",
"s3:ListObjects"
],
"Resource": "*"
},
{
"Sid": "VisualEditor1",
"Effect": "Allow",
"Action": "s3:*",
"Resource": [
"arn:aws:s3:::mybucket/*",
"arn:aws:s3:::mybucket"
]
}
]
}
I'm quickly running out of hair as I seem to be pulling it out at an alarming rate. No doubt this is yet another schoolboy error, so appreciate your time in reviewing.
