Is this a Widget or a Field Level DX component? I believe you are using Visual Studio Code for your development, as it can help highlight errors. I was wondering if you are able to test it through Storyboard. Did you notice any issues in the console logs while storyboard testing?

@Mamatha Adiraju The error occurs because your custom component's configuration is missing required fields like label, format, name, or source. Check the JSON file defining the component and ensure each property in the properties array includes these fields with proper values. For example, each property should have a name (e.g., "Property1"), a label (e.g., "Label for Property1"), a format (e.g., "string"), and a source defined as an object with details like type and fieldName. Validate your JSON using an online schema validator to catch formatting errors. Once corrected, upload the updated configuration to Pega and test. Refer to Pega’s documentation on DX components for additional guidance, or enable debug logs to get more details if the issue persists. Let me know if you have any questions, thanks
