Authentication failed

[mat-l]

Dear all, I am having trouble with the authentication with my MongoDB GridFS while using depot.

As mentioned in the main page (https://pypi.org/project/filedepot/) of depot I am running the following commands:

from depot.manager import DepotManager

# Configure a *default* depot to store files on MongoDB GridFS
DepotManager.configure('default', {
    'depot.backend': 'depot.io.gridfs.GridFSStorage',
    'depot.mongouri': 'mongodb://admin:admin@100.x.x.x:27017/test'
})

Out[2]: <depot.io.gridfs.GridFSStorage at 0x24281ead908>

depot = DepotManager.get()

# Save the file and get the fileid
fileid = depot.create(open('C:/Users/xxx/Documents/mongodb/mineral.jpg'))

which results in the output:

Traceback (most recent call last):

pymongo.errors.OperationFailure: Authentication failed.

I am currently running MongoDB 4.2.8 Community within a Docker container on Ubuntu 18.04.

Can anybody give me a hint how to fix the authentication problem with depot? The mongodb-compass program and Python "pymongo" lib are working with the credentials: mongo_uri="mongodb://admin:admin@100.x.x.x:27017" client = MongoClient(mongo_uri)

Best regards matl

I noticed that in the command mentioned on top, I have used a non exisiting database called "test". While using the existing database "admin" the command:

# Save the file and get the fileid
fileid = depot.create(open('C:/Users/xxx/Documents/mongodb/mineral.jpg'))

leads to this error message:

You are opening the file in text mode on Python3, which leads to trying to decode it as text. Try to replace open('C:/Users/xxx/Documents/mongodb/mineral.jpg') with open('C:/Users/xxx/Documents/mongodb/mineral.jpg', "rb")
