Flask Deployment to AWS getting permission errno 13 - python-3.x

Question

I have working app on the localhost but when I deployed to the AWS it shows several errors.It can receive my sent image but it cant save it. I tried change permissions with chmod,still its not working. This is first time i am deploying flask app,so I dont know much about i My code is as follow:
***modules***
ImageFile.LOAD_TRUNCATED_IMAGES = True
app = flask.Flask(__name__)
#app.route('/', methods = ['GET','POST'])
def hello():
return 'hey there!!!'
#app.route('/imageupload', methods = ['GET','POST'])
def handle_request():
try:
imagefile = flask.request.files['image']
filename = werkzeug.utils.secure_filename(imagefile.filename)
print("\nReceived image file name:" + imagefile.filename)
imagefile.save(filename)
print("hey")
for image in glob.glob('./frames/*.*'):
img_filter(imagefile,image)
json = flask.request.values['Id']
return {"status": "true","message": "Uploaded Successfully", "Id": json }
except:
return {"status" : "false"}
if __name__ == '__main__' :
app.run()
And these are the errors :
Received image file name:1.jpg
ERROR:image_flask:Exception on /imageupload [POST]

Answer 1

you don't have the right permission. Try to open first the folder with chmod -R 700 /home/ubuntu/pic-edit/
Please note open the permissions like this can be dangerous. Rather I would assign the permission to the "Flask" - Running user
Further for investigations under which user are you running the flask app? How do you start the app?
Also you might change the handle func to:
def handle_request():
try:
f = request.files['file']
f.save(secure_filename(f.filename))
json = flask.request.values['Id']
return {"status": "true","message": "Uploaded Successfully", "Id": json }
note you nead to import from flask import request

Answer 2

I got it where I went wrong, that is because of permissions to the folder. I already tried "chmod 755" to it but it did not worked. After that I tried
chmod a+rwx
And that work fluently.
