When creating a joined view layer with field statistics while the parent layer is sync-disabled, the Join_Count field generated automatically inherits the field type and domain of the field of the performed statistics.

Solución alternativa

• Delete the minimum or maximum value of the original small integer field in the first layer so the Join_Count field and the max stats field do not have a domain and the resulting view layer is able to load.
• Create an integer field instead of small integer and use 'Calculate field' to calculate the values from the small integer field. Then use the regular integer field for the field statistic.
• Enable sync.
