Losing around 10% of submissions

[adityac95]

Thank you so much for this valuable tool. I've had a few issues recently where data from around 10% of my participants did not get saved properly to OSF despite them reporting no issues with doing the experiment. I haven't been able to identify a pattern for why this might be the case, but I am wondering if this is a known issue and/or others have experienced this?

I've experienced this occasionally but wasn't sure it was a DataPipe problem. Sounds like it could be. I'm gonna look into it!

@Bankminer78 we should think about how to test this carefully.

Hi, I have experienced something similar. I lost about 50% of submissions in my last run of the experiment (that is, more people are indicated as having completed the study than there are datapoints). My session limit had not yet been reached but somehow no files (.csv format) were saved to osf beyond a particular amount. I don't think files are being overwritten because file names are unique subject id strings. Weirdly, when I run myself on the experiment as a test, a new file is created and the completed session count on datapipe goes up. I wonder if there is an internal cap to the number of synchronous sessions or something? I am not collecting much data at all (<100 subjects)
