![]() ![]() Below is the sample snippet on how you can ensure to check the response has 200 status code and valid content type as application/json if ( If you are making requests to API, make sure to check the response status code is 200 (OK) and then perform JSON parse. Output Other Possible Solutions Ensure HTTP 200 status code and valid content type as application/json # Python program to solve JSONDecodeError: Expecting value: line 1 column 1 (char 0) Now that we have added the proper content to the books.json file when we run the same code again, we get the below output. Validate if the file is not empty and has proper JSON content. The solution is simple and straightforward. Note: In this case, if the JSON file is not found, you will get a FileNotFoundError: No such file or directory Solution The json.loads(j.read()) tries to load the JSON content and parse the JSON, and during that time, if it’s not well structured, you get a JSONDecodeError. : Expecting value: line 1 column 1 (char 0) Raise JSONDecodeError("Expecting value", s, err.value) from None ![]() Obj, end = self.raw_decode(s, idx=_w(s, 0).end())įile "C:\Users\abc\AppData\Local\Programs\Python\Python37\lib\json\decoder.py", line 355, in raw_decode Output Traceback (most recent call last):įile "c:/Projects/Tryouts/main.py", line 6, in įile "C:\Users\abc\AppData\Local\Programs\Python\Python37\lib\json\_init_.py", line 348, in loadsįile "C:\Users\abc\AppData\Local\Programs\Python\Python37\lib\json\decoder.py", line 337, in decode import jsonįile_path = "C:/Projects/Tryouts/books.json" It always expects the proper JSON structure. However, since the JSON file is empty, the JSON module will throw a JSONDecodeError when we try to read the empty content. In this example, we are trying to load a JSON file from the specified path and print the contents of the JSON file. Let me demonstrate with a simple example of replicating a JSONDecodeError, and we will look at solving the same. Rather it comes in string format, which in turn throws a JSONDecodeError while parsing the response.Īlso, read the Python JSONPath tutorial Example JSONDecodeError: Expecting value: line 1 column 1 (char 0) ![]() The response type doesn’t come in the format of application/json.The JSON response is not structured properly.The response might be in some other format such as XML, HTML, etc.In most of cases, you get json.loads- JSONDecodeError: Expecting value: line 1 column 1 (char 0) error is due to : Let us take a look at the possible causes of JSONDecodeError and how we solve this issue in our code with some examples. JSONDecodeError: Expecting value: line 1 column 1 (char 0) If you are working with APIs and trying to fetch and parse the JSON data while making the HTTP or curl requests and JSON response is not well-formed, Python will throw : expecting value: line 1 column 1 (char 0).
