Error when trying connect to Mongo instance.

[pwrdby]

Hello !,
I'm trying run monstache:6.0.9 with ES7 and MongoDB 4.
I have these 3 applications (ES, MDB, MStache) in docker file similar like here https://github.com/rwynn/monstache-showcase.

Unfortunetly, I can't connect monstache with mongoDB, I've receved error:
ERROR 2019/08/27 17:46:46 Unable to connect to MongoDB using URL mongodb://REDACTED@mongo1:27017: auth error: sasl conversation error: unable to authenticate using mechanism "SCRAM-SHA-256": (AuthenticationFailed) Authentication failed.

If I connect to mongo instance via Mongo Compass with user:password, what I use in .toml file, connection works.

I also tried a test from this repository (docker/test) and this ended with error:

`ERROR: for sut Container "c1a00a98f03d" is unhealthy.

ERROR: for monstache Container "c1a00a98f03d" is unhealthy.
ERROR: Encountered errors while bringing up the project.`

Thank You for Your time and answer!

@pwrdby can you try monstache v6.1.0 recently released? It uses the latest go driver from MongoDB at v1.1.0.

If that doesn't work you may want to search the golang driver for related issues and create one yourself. Unless you can spot something wacky in the monstache code I think this would be a driver issue.

Also, if the test in docker/test did not work, that might indicate some issue with docker. The test in docker/test is run by Travis CI on each commit and last was healthy. Here is the log for the latest release.

@rwynn so, I tried monstache v6.1.0 and still same problem. I also tried test one again, I run only elastic service and saw the exit code 78, when I put it to the google the solution for this was here laradock/laradock#1699. Then I ran test with all services and it passed :).

But issue in my configuration was still there, so I change the root user and password, like you had set in the test and then it works! It's strange, I had in my password numbers and chars like '!' ... could be this the issue ?

@pwrdby if you have special characters in your username or password you would need to url.QueryEscape those characters. For example, see the output in this go playground for what you might need to put in your config file...

https://play.golang.org/p/_jBLodshn-0

Of course, don't run with your actual creds in a go playground! Instead run go offline.

If you look at the go driver source code that interprets the URL provided in the config, you will see it does a url.QueryUnescape on both the given username and password.
