How To Fix “Unexpected End of JSON Input Janitor AI”
Is error ko fix karne ke liye, pehle invalid JSON ki wajah identify karni padegi, fir usko correct karna padega. Yahan kuch tips hai:
1. Validate the JSON first
Kisi JSON validator jaise jsonlint.com ka use karke apne JSON data check kare aur koi bhi syntax errors pakde. Validator missing commas aur quotes identify karega taki aap unhe parse karne se pehle fix kar sake.
2. Handle errors gracefully
Apne JSON parsing code ko try/catch blocks mein wrap kare taki koi bhi errors pakad sake. Yeh “Unexpected End” error ko gracefully handle karne deta hai:
try {
const data = JSON.parse(json);
// process data
} catch (err) {
// handle error
}
Catch block mein aap error identify kar sakte ho aur handle kar sake.
3. Check the data source
Agar aap JSON kisi external API ya server se le rahe ho, toh browser ke DevTools ki Network tab mein raw response check kare. Verify kare ki data complete hai, expected structure match karta hai, aur sahi Content-Type header hai jaise application/json.
4. Encode/decode properly
Agar aapko JSON encode ya decode karna hai (jaise Base64 mein), toh ensure kare ki aap data corrupt na karke kar rahe ho. Chote JSON ke saath pehle test kare.
5. Handle data type mismatches
Agar aapka code kuch specific data types expect karta hai jo parsed JSON se match nahi karte, toh parse karne se pehle data transform karna pad sakta hai taaki type errors se bach sake.
6. Standardize data structures
Inconsistencies in data structures ko eliminate karke standardized expected format pe chale. Yeh parsing ke time surprises se bachata hai.
