VAR Model error message: the exogenous variables may not be collinear with the dependent variables, or their lags

[Julia Sophie]

Hello everyone, I would like to do a VAR analysis. I have the following model: My main hypothesis is the effect of Violent Conflicts on Innovation Performance, with the mediators Opportunity Recognition and Entrepreneurial Activity.
I would like to first determine the situation between Violent Conflicts and Opportunity Recognition, then Opportunity Recognition and Entrepreneurial Activity, then Entreprneurial Activity and Innovation Performance.
Violent Conflicts -> Opportunity Recognition -> Entrepreneurial Activity -> Innovation Performance
Now I entered in Stata the command to the VAR for Violent Conflicts and Opportunity Recognition. However, I get the following error message:
the exogenous variables may not be collinear with the dependent variables, or their lags
Can anyone tell me where the problem is?

Not sure var works with panel data. pvar or xtvar are options. The error may be triggered by repeated dates. Dump the exog part and see what happens.
