TypeError: Converting circular structure to JSON

Here’s a solution for a similar error

TypeError: Converting circular structure to JSON (...)

Hi @SaraCal, It seems like passing in the names of ‘cue1’ and ‘cue2’ when setting opacity for the rest of your stimuli inside of ‘fixation_cueRoutineBegin’ is causing the error. Could you please try passing in numeric values instead? If your intention is for eg. ‘cue1a_main’ to have the same opacity as ‘cue1’ as a result, you should be able to just use ‘cue1.opacity’ I believe. I hope that solves the problem, here to help if not.

@pc1, this error has occurred because you set the text of a text component using a text component object, rather than actual text. In the PRACTRIAL routine, the text component called PRACtext_2 uses a text component called text. This has happened because a column in your conditions file matches the name of one of your text components. The easiest fix will be to change the name of your "text" text component to a unique name.
