Error: System.JSONException: No content to map to object due to end of input. What does this error mean?
After running the above class, I am getting output, but it is generating some errors on some lines. I have tried everything. But I am at a loss here. Can anyone please help me understand if there is something I can add or if I am missing something? no content to map due to end-of-input
No content to map due to end-of-inputIf can occur. If you are getting any empty string or a white string, you can try out the code:
JsonParser objJsonParser = (JsonParser) JSON. deserialize(‘ ‘, JsonParser.class):You can also go for proper string null, empty, and blank checks before applying the deserialization method. The String class contains the ‘is not blank’ method. You can use this method, and then you can use your deserialization logic.

The error message "System.JSONException: No content to map to Object due to end of input" typically occurs in a context where JSON data is being processed or parsed, such as when deserializing JSON into an object in Apex, Salesforce's programming language.
This error message indicates that the JSON parser encountered the end of the input string unexpectedly, meaning that the JSON data being processed is incomplete or empty. Here's what each part of the error message means:
System.JSONException: This indicates that an exception of type JSONException occurred. JSONException is a Salesforce-specific exception thrown when there is an issue with JSON parsing or serialization.
No content to map to Object: This suggests that there is no valid JSON content available to be mapped to an object. In other words, the JSON data being processed is either missing entirely or is not in a format that can be deserialized into an object.
Due to end of input: This specifies that the error occurred because the JSON parser reached the end of the input string unexpectedly. This could happen if the JSON data is truncated, incomplete, or if there are syntax errors that prevent proper parsing.
To resolve this error, you'll need to ensure that the JSON data being processed is valid and complete. Here are some steps you can take:
Check JSON Data: Verify that the JSON data being parsed is correctly formatted and contains the expected content. Ensure that all opening and closing braces, brackets, and quotation marks are properly matched.
Inspect Data Source: If the JSON data is being retrieved from an external source, such as an API response, verify that the data source is providing valid JSON and that there are no issues with the data transmission.
Handle Edge Cases: Consider scenarios where the JSON data might be empty or null, and implement appropriate error handling in your code to handle such cases gracefully.
Debugging: Use debugging techniques, such as logging the JSON data before parsing it, to inspect its content and structure. This can help identify any issues with the JSON data that might be causing the error.
By addressing any issues with the JSON data and ensuring that it is properly formatted and complete, you should be able to resolve the "System.JSONException: No content to map to Object due to end of input" error in Salesforce.
