IDE Fatal Error: NullPointerException

[smcoll]

PyCharm 2016.1.4 reported a fatal error. The notice came when i opened a second IDE window, but i don't now if that was when it occurred, or if that was when i was notified: Exception in plugin Env File. Today at 9:19 AM. Occurred 2 times since the last clear. Unread.

This is all the context i have, unfortunately.

null
java.lang.NullPointerException

Thanks for the report - I'll look into it and will try to release fix soon.

@ashald i ran into this again today. Do you need anything to help debug?

[ashald]

@smcoll I tried to reproduce an error but without any success. Can you share more details what actions lead to it?

[ashald]

BTW, are you running CE or PE version?

[smcoll]

Good news: figured out how to replicate the issue. The selector for the type of file (env/yaml) next to the file selector was somehow empty. Once i selected .env the issue sorted itself out. i don't know where the empty option came from; maybe that was an artifact from an earlier version of the plugin?

i'm on 2016.2.1 PE now.

Unfortunately I wasn't able to reproduce the issue. Will appreciate if people can comment whether they still experience the issue and whether there is a sure way to reproduce it.

@ashald happened to me today. I think the latest PyCharm update (which I installed yesterday night) somehow cleared my .env selection for the file type setting?

It might be enough to just add some graceful handling to that field being empty.

This should be fixed in v2.0 so closing the issue.
