Bad control character in string literal in json

When you encounter the error “bad control character in string literal in JSON”, it means that there is an invalid character present in a string within your JSON data.

JSON (JavaScript Object Notation) is a lightweight data-interchange format that uses human-readable text to transmit data objects. It is commonly used for transmitting data between a server and a web application. In JSON, strings are represented as a sequence of Unicode characters.

However, not all Unicode characters are allowed within JSON strings. Control characters, such as certain whitespace or control characters used for formatting or control purposes, are not allowed. These characters can cause parsing errors in JSON.

To fix the “bad control character in string literal in JSON” error, you need to identify and remove the invalid control character from your JSON string. The specific steps to do this depend on the programming language or framework you are using to parse and handle JSON.

Here’s an example to illustrate the issue:

{
  "name": "John\u0008Doe"
}

In this example, the JSON includes a control character (\u0008) within the value of the “name” field. The control character \u0008 represents the backspace character.

If you try to parse this JSON, you will encounter the “bad control character in string literal in JSON” error.

To fix this issue, you can remove the invalid control character from the string:

{
  "name": "JohnDoe"
}

The updated JSON no longer contains the control character, and it should be parsed without any issues.

Remember that the specific control character causing the error may vary. It can be any character that is not allowed in JSON strings.

Ensure that your JSON data adheres to the JSON specification and that there are no invalid control characters in your string literals.
