Thanks for replying to my PM with your experiment URL. Before I ask @apitiot to investigate, please could you clarify something.
In a PsychoJS experiment, this means that the data won’t be saved unless incomplete data saving is turned on and the escape key is pressed twice. Sessions don’t show up as aborted when daisy chaining to Sona in PsychoJS, so please could you clarify why they need to be in lab,js and how the data was getting saved?
Here is a similar issue which I think was solved by improved daisy chaining.
