PasCdfDone errors from callbacks

I am using using SKILL to create a single instance and set some properties.  This code generally works fine on other PDKs but on this PDK I am sometimes seeing an error (though the error is wrapped in a warning (?!)):

WARNING* (CDF-262): Cannot call doneProc SKILL function '(apply GFcdfDone (db:0x3015251a))' because a SKILL error '*Error* PasCdfDone: failed to find valid initialization data!'.

I'll include the full transcript below but basically it creates a schematic, instantiates a single instance with `dbCreateParamInst` and then sets some parameters.  When the callbacks are invoked using `CCSinvokeCdfCallbacks` I am seeing this `PasCdfDone` error message even though I am using the flags on the `CCSinvokeCdfCallbacks` call which usually fixes that problem.

The device ends up correctly instantiated with the properties set correctly but the warning seems to imply that some part of the callback code has not executed correctly and so some parameters of the device might not be correct.

The really odd behaviour is that this is what happens the first time I run the code.  But if I do the creation and instantiation again then the error does not appear - as you can see below.

I am running this in Virtuoso IC23.1-64b.ISR15.37.   The version of CCSInvokeCdfCallbacks is CCSinvokeCdfCallbacks.il 04/25/22.17:40:23 1.19
