Incorrect Data Type Errors



When a user finishes the final exam in the content and receives a score, a number of JavaScript warnings pop up:

LMSSetValue Error: cmi.interactions.1.correct_response.0.pattern to [n/a]Incorrect Data Type

LMSSetValue Error: cmi.interactions.1.student_response.0.pattern to [n/a]Incorrect Data Type

I get probably ten or fifteen of these -- maybe a pair for each question I missed (interactions.12, interactions.35). On a second attempt, the interaction numbers are higher. This is a problem in both our LMS and in SCORM Cloud.


By default, the SCORM Engine validates all interactions against the SCORM specification...n/a is technically invalid, but we do have a package property to help this out. If you disable 'Enable Validation of SCORM Interaction Results' that lives on the compatibility tab, you should not receive this error anymore.

    I am getting very similar errors and have seen the answer to "Disable 'Enable Validation of SCORM Interaction Results' but do not know where to find this. Is it in Lectora or the LMS that I am using?

    Hey Tara, 

    If you are using an LMS that uses our SCORM Engine ( then that option should show up in the package property editor if they chose to expose that option.  What LMS are you using?

    Thank you,
