I am trying to export data driven pages using Arcpy butmxd.dataDrivenPages.pageCount return 0.
Here what i am doing... first I am replacing the data source of the layer then refreshing the data driven pages and after that using for loop trying to export data driven pages in jpeg.

<SPAN class="" style="color: var(--blue-800); border: 0px; font-weight: inherit; font-size: 13px;"><SPAN style="background-color: #e4e6e8;">lyr.replaceDataSource(path_of_data_source, "SHAPEFILE_WORKSPACE", "data_source_name")
