The analyzer identified a compatibility issue. Parameters have a multiValue property that can be either true or false. This property controls whether the parameter accepts multiple values or a single value.
The parameter's multiValue property is not consistent at the current version and the selected target version.
This compatibility issue cannot be addressed automatically. Try the following:
- Use a later target version in which the compatibility issue is not present.
- Modify the model or script tool to use an alternative, if one exists, to the problematic tool or parameter.
