Hello,
We have been using a JS function within our Survey123 surveys for months, with no issues. The JS function was a single-line one, which simply created an 8-digit timestamp. It was working fine on Nov. 15. Suddenly (Nov. 17), the destination field in the corresponding feature layer in AGOL is null.
We have tested creating a survey from scratch, in Connect, starting from the Advanced template and simply modifying it to introduce a calculate row with a "HelloWorld" JS function. Same result.
We have tested publishing the survey to 2 different AGOL organizations. Same result.
We have updated Connect from 3.13.239 to 3.13.249 (the latest as of this moment). Same result.
If we remove the JS function and introduce whatever other data-creation method (like, for instance, pulldata("@property", 'language')), the data is created fine and populates the target feature layer.
We are scractching our heads here...
