runtime error: invalid memory address or nil pointer dereference

[Elycin]

Hi there,

Before going into any details, I looked to see if there are any previous issues in relation to this one, I found #7 but this seems to be slightly different, so I'm posting here to look for help.

I have a proper configuration as follows of timeliner.toml in my root directory that I specify via -config /root/timeliner.toml

I got timeliner successfully working with google photos last night and woke up this morning to find that the process has stopped with the following stack trace:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x10 pc=0x7c9862]

goroutine 10 [running]:

Any ideas on how I can fix this?

Thanks in advance.

What version are you running (commit SHA) and what is the command that you're running?

[Elycin]

@mholt I cloned the repository and compiled the application using the master branch last night. (41cce90c698bf35d1f3985b5b50fa029d9ed9fef).
The command I am running is timeliner -v -config /root/timeliner.toml get-latest google_photos/[REDACTED]@gmail.com

Please let me know if there's any other information I could provide.

Cool, thanks. I'm pretty sure I simply forgot to do a nil check on that line. I haven't tested this myself, but would you mind pulling the latest commit and trying again?

(Edit: I quickly decided to move the nil check to a different line, so I pushed another commit that I think is more correct. Commit cf15516.)

That looks to have solved it. Thanks for the quick help! Here's a console replay: https://asciinema.org/a/RVYcicoORZOMcW28wNKkc3OG3
