SyncFusion 18.4.30 Update - map not rendering data since release

[Lee]

Hello,

I am using the map component and SyncFusion 18.3.0.53 which is working. I am trying to update to the latest version 18.4.41 and having problems with the map continuing to work.

I have read the release notes of 18.4.30 where I see that maps have had a few changes. I made the changes that I thought were required but I am receiving some logs that explain:

Error Log

'The requested operation requires an element of type 'Object', but the target element has type 'Array'

This is caused by the 'ShapeData' parameter, which is expecting 'Object'. This is pointing to a property of type 'Object' already, which is JSON map data that has been deserialized into an 'Object'. 

If the component cannot accept data that has been deserialized into an 'Object' then how are we meant to populate the map with data? I could not see any mention of the ShapeData changing how it works with data in the release notes.

Thanks,

Lee

Hi Lee,

Thank you for your update. 

  

When we checked the provided JSON file with our fix in the Maps component, the reported exception is not reproduced. So we have resolved this issue. But the provided map shapes are not rendering properly in the component. However, we will include the fix for the reported issue in our weekly NuGet release which is expected to be available by the mid of February 2021.
