[Solved] Initial single server setup with Ubuntu 14.04.4 - ./platform not work - panic: runtime error: invalid memory address or nil pointer dereference

Troubleshooting
1

I’ve configured a single Ubuntu 14.04.4 server and have been following the Ubuntu 14.04 LTS guide: http://docs.mattermost.com/install/prod-ubuntu.html
When I run ./platform the service does not work.
This is the result of execution:

root@Mattermost:/home/mattermost/mattermost/bin# su mattermost
mattermost@Mattermost:~/mattermost/bin$ ./platform
panic: runtime error: invalid memory address or nil pointer dereference
[signal 0xb code=0x1 addr=0x0 pc=0x6198b0]

In this post: Single-server, CentOS 7 initial setup -- Won't launch as service indicates create the log file mattermost.log and assign the correct permissions, but does not influence in the result.

Any help would be appreciated.

Sorry, I had not set, the version is the Current Stable Release (v2.0.0).
Regards.

Hi elrublog,

The error your getting seems to intimidate that Mattermost can’t find or read its configuration file. Can you verify the the file is present, there are no errors in the JSON and the user running Mattermost has read write permissions to it?

I had the exact same problem with 2.0.0 on Ubuntu 14.04.4 64 bit - it turned out I was missing a trailing comma in the config.json file on the second line that I edited to connect to the database. I also entered postgresql instead of postgres like I should have.

Thanks for posting your solution, I had missed the , too!

Hello elrublog,

I have the same issue but the solution doesnt seem to work for me.

This is the error below:
v3nd1tt@v3nd1tt:~/mattermost/bin$ ./platform
panic: runtime error: invalid memory address or nil pointer dereference [recovered]
panic: interface conversion: interface is runtime.errorString, not string

Kindly help me resolve.

I went through a second time to double check my config.json but i still get this error.

Hi Ewurama,

It does seem to be a problem with your configuration. Can you try reverting to the default configuration and making your changes again?

Thanks.
