I've recently programmed a cognition.run experiment and subjects get stuck on a screen that says "sending data to the experimenter..." (see attached screenshot). This was never an issue when I ran very similar studies on the platform, it used to just be a blank white screen. Any idea what could be going on here? (also I don't seem to be able to download individual csv files for unifinished runs, it says "oops page not found! when I try to do that. I assume it's unrelated? but just another recent issue that I never had before). Thanks for any and all ideas/help!

I wonder if this is related to the recent 7.0 update that @javidalpe made. I think we'll need his guidance here. |

@MTuttle6 which version of jsPsych are you using in cognition.run? |

Looks like I've got it set to 6.2.0 |

Oppps! Thank you for reporting this @MTuttle6. This was a cognition issue. It should be fixed now. It was a stupid one. I forgot to remove the message "Sending data..." once the data was sent to the server 🤦 . The impression was the user was stuck there, unable to close the window. I didn't notice this because I always use the on_finish callback to redirect the browser or show a message. BTW, this message was an idea from @jodeleeuw 👏 |

Hi folks! Today, I get exactly the message as MTuttle6 describes when running an experiment that run perfectly last week Friday. I need fast help here, as I need data coming in today. My code on cognition.run is pasted below. The problem lies in variable conclusion which should show participants a conclusion screen and provide a link to Prolific. But it never shows!!! Instead, I get the message like MTuttle6 has reported and the screen stays white. Thank you so much for your help!!! //------------------------------------------------------------------- randomize = true // present different set sizes in random order. if false, set sizes will be presented in ascending order // randomly choose a list: 1 or 2 var conceptual_stimuli var possibleLetters = ["F","H","J","K","L","N","P","Q","R","S","T","V"] var nSets = setSizes.length } test_setSizes = test_setSizes.flat(1) //test_setSizes = [2, 2] var sumDemoTrials = 0 var setSizesFullDemo = decisionDemo_setSizes.concat(letterDemo_setSizes) var sum = 0; var decisionDemo_stimuli = jsPsych.randomization.sampleWithoutReplacement(practice_stimuli, 5) var sum = 0; var decisionTest_stimuli = jsPsych.randomization.sampleWithoutReplacement(conceptual_stimuli, sum) // The new variable with the resampled order of my conceptual decision target stimuli, adjusted to the selected set sizes var lingtrials = decisionDemo_stimuli.concat(fullDemo_stimuli, decisionTest_stimuli) // Combine the three types of trials into one array var letterTrial = 0 //keeps track of number of letter trials gone by var selection=[] var trialArrays = [] } // Define the instructions var welcome = { Vajuta klaviatuuril ükskõik, mis klahvi selleks, et jätkata. ,choices: ['Weiter >'], }; var instructions = { type: "html-button-response", stimulus: <p> In diesem Experiment lösen Sie einfache Aufgaben und erinnern sich gleichzeitig an Buchstaben, die Sie zwischendurch auf dem Bildschirm sehen.
