![]() Use this method if the code that's throwing the error looks like this: JSON. The body text is logged to the console for examination. Instead of trying to parse the response body from the server as JSON it is processed as raw text. This line logs the rejectionReason from the rejected response.json() promise and the responseClone so it can be examined if needed (the HTTP status code is often useful for debugging, for example). This second function will be called if the promise from response.json() is rejected (i.e. This line populates the responseClone variable with a clone of the response received from the server.Ī second function argument is passed to the then() function that follows the response.json() call. hi devs please im facing and issue in my laravel project i created the database and now trying to migrate it but i get this error when i do PHP ARTISAN. When I click the link to the image, it only opens the image up on a new page with a dark background. Cloning the response to responseClone provides two copies of the response body to work with one in the original response to use with response.json() and another to use with responseClone.text() if response.json() fails. When response.json() is called the body of the original response is read, which means it cannot be read again when handling the JSON parse error. Here's an explanation of each line with a numbered comment:Ī responseClone variable is required to hold a clone of the response object because the body of a response can only be read once. I search over google and try to find out reason but I am not satisfied. but jest only works with commonjs and can’t handle. If you run jest directly, the following happens: the babel-config will not be adjusted for the test environment, which means ES6 modules will not be transpiled to commonjs. import express from 'express' Synta圎rror: Unexpected token import. You should not run jest directly, but instead run it with the command that vue-cli defined for you in package.json. You can add a function to handle the error and display the raw text of the response body from the server and log it to the console (see notes about commented lines below): var responseClone // 1Ĭonsole.log('Error parsing JSON from response:', rejectionReason, responseClone) // 4Ĭonsole.log('Received the following instead of valid JSON:', bodyText) // 6 When I was run it via simple command 'pm2 start test.js'. ![]() In this case the error is thrown when response.json() tries to run and fails to parse the data from the server as JSON. Use this approach if your code looks something like this: fetch('') To do this you need to log the data you're trying to parse to the console. To fix this error you need to figure out why you're getting HTML (or something else) instead of the JSON you expected. Valid JSON cannot begin with a < character, so the JSON parser knows immediately the data isn't valid JSON and produces one of the error messages mentioned above. This guide will help to fix Synta圎rror: Unexpected token or ) instead of JSON. ![]()
