I run a lasso for inference model using double selection:

dsregress depvar i.variable_of_interest1 i.variable_of_interest2, controls($cont i.($cat)) rseed(12345)

And store the estimates:
estimates store ds_plugin

I can look at the controls selected for the dependent variable:
lassocoef(ds_plugin, for (dapvar))

What I would like to do is look at the controls selected for the variables of interest - so at the moment I am writing:
lassocoef(ds_plugin, for (variable_of_interest1))

However I get an error with this:

can not find result for variable_of_interest1
r(111)

I am inputting the same code as in the lasso manual so am unsure why it is not working for me. If anyone could explain that would be really helpful
