I am facing the issue of “conformability error (503)” while running the synth command in Stata 15.1.
My data looks like below

Dis qtr od fem_hd poor rural
101 176 .6428571 .0714286 0 .6428571
101 186 .7058824 .1176471 .1764706 .7058824
105 162 1 1 0 1
105 184 .4 .4 0 .8
110 180 .4285714 0 0 .7857143
205 168 .75 0 .25 1
205 176 .7407407 .0185185 .0925926 .3888889
600 187 .7482759 .0396552 .2948276 .7775862

qtr (min 152- max 221) is time variable and Dis is the Panel variable

tsset dis qtr
(it is unbalanced data with gaps)

I run the following command

synth od fem_hd poor rural, trunit(600) trperiod(174)
and it give conformability error 503

I have tried the synth2 version correcting the do file at line 3 and 672 and then synth_wrapper do file at 35

synth2 od fem_hd poor rural, trunit(600) trperiod(174)
but it give the same error.
