when I use OccBin to solve my model, which involves borrowing constraints similar to JME 2017, collateral constraints and macroeconomic asymmetrics, I met such an error.

Does that mean that there is sth wrong with my setting of “constraint=” or “constraintr\_relax=”?

What can I do to fix it? (I use the toolkit\_files\_4.5., in the forum).

Does anyone have any advice on how to fix? Please do help!

Thanks!

Without the files, it is impossible to tell. Note that a 4.6-compatible version of Occbin is at [GitHub - JohannesPfeifer/Occbin\_update](https://github.com/JohannesPfeifer/Occbin_update)

Hi,

May I ask if you have solved your problem. I also have a problem with this toolkit, but my problem is on steady state as follow

Unrecognized field name “ys”.  
Error in solve\_one\_constraint (line 49)  
eval([Mbase\_.endo\_names{i,:} '_ss = oobase_.dr.ys(i); ']);

Do you have any ideas about this problem? Thank you
