Could you please let check it and let me know

dipankar08 commented 4 years ago

I have the same issue.

DarkAdventurer93 commented 4 years ago

I have the same issue. But I know why now. Becasue I use a invalid key , so you guys should check your key, it seems the key could not contains "/".

pilgr commented 4 years ago

Thanks, that's a good point. I've added a note to the readme. Since keys are used as file names to store the data, the special symbols like \ can't be used.

rmirabelle commented 3 years ago

Same error for me. Intermittent. My key is perfectly valid. 19 out of 20 saves work correctly, then bam. Clearly the synchronization lock for reading from/writing to the file intermittently fails. This is a big deal. I'm doing the read/write from various contexts - sometimes on Main, sometimes from coroutine (IO dispatcher), etc.
