Dear support staff,

I very much appreciate your help. I think it must be something in the lavaan syntax, but after checking and rechecking and reading up on other reported issues, I can't find what the issue is.

All the best wishes

Dear @larsvantuin, I think attaching the zipped .jasp file has not worked. Could you try that again?

[larsvantuin]

Dear Julius, Here is the zipfile again. Hope it works this time. I had zipped the CSV-file iso the JASP-file  I will also upload it on the site Thank you so much for your support. BTW: I had tried the same lavaan syntax in the PLS and that one worked. Strange. All the best Lars

Hi Lars, the issue was with "ML" as estimator when data is categorical. I am very sorry about the uninformative error. The fix is already in (https://static.jasp-stats.org/Nightlies/) (that would be in the "development" branch).
It is important we get the next version released soon.

Hi Julius, thank you so much for looking into it. I followed the link to Nightlies, but I am unclear about which file to download. Can you help me with that?
