Example warning message
Warning: -1 is not an element of the Time index.
Cause
Your model is evaluating a dynamic loop. During this evaluation, an expression attempted to access an element (e.g., using Subscript) that does not correspond to an element of the Time index. This might occur, for example, if you tried to use a value from a time period before your first time period.
Remedy
This might be exposing a logical error. But if this is intention, this is only a warning, so you can ignore it, e.g.:
Change:
X[Time = v]
to
IgnoreWarnings(X[Time = v])
or you can make the logic explicit:
If v >= 0 Then X[Time = v] Else Null
Or you can specify a default value:
X[Time = v, defval: 0]
The defval is used when v is not found in the Time index.
