    Cause

    The error “”message”: “Missing Authentication Token”” might have a variety of causes. However, the first cause you should consider is Forgetting to Deploy.

    Solution

    If you just test your endpoint in the console and see the desired results without implementing your changes, you will never be able to see your API in the real world. Using Gateway’s built-in deployment functionality, you can publish new changes to the Internet.

    As shown in the picture above, go to your API and choose the Actions tab. When you click Deploy API, you’ll be sent to the configuration method.

    If you’ve already built up stages, deploy to one of them; if you haven’t, build one with whatever name you choose. If you’d like, you may leave a message, but otherwise you’re ready deploy.

    Remember that you must redeploy your API after each modification to ensure that those changes are published to the Internet.

    I hope that by doing so, you’ll be able to solve your problem.

    how to solve “ActionController::UnknownFormat” error

    Cause: The “ActionController::UnknownFormat” error occured because you set HTML as the only format to react to. As a result, you missed a format in a response that you wish to support. Solution: When writing a blog post, you should consider an action where you want to reply to HTML and JSON queriesRead more

    Cause: The “ActionController::UnknownFormat” error occured because you set HTML as the only format to react to. As a result, you missed a format in a response that you wish to support.

    Solution: When writing a blog post, you should consider an action where you want to reply to HTML and JSON queries to help your page be able to support an Ajax request. This is what it may look like:

    class BlogPostsController < ApplicationController
def create
@blog_post = BlogPost.new(blog_post_params)
respond_to do |format|
if @blog_post.save
format.html { redirect blog_post_path(@blog_post) }
format.json { render json: @blog_post.to_json }
else
render :new
end
end
end
end

    When the blog post fails validations and is not saved, this error is raised. within the response block’s scope of word formatting blocks, You must use the render command. If you were to rewrite this to account for failure, it would look like this:

    class BlogPostsController < ApplicationController
def create
@blog_post = BlogPost.new(blog_post_params)
respond_to do |format|
if @blog_post.save
format.html { redirect blog_post_path(@blog_post) }
format.json { render json: @blog_post.to_json }
else
format.html { render :new }
format.json { render json: @blog_post.errors.to_json }
end
end
end
end

    And now, there will be no more unintended ActionController::UnknownFormat exceptions that all formats have been declared.

    The best way to solve “_registerComponent(…): Target container is not a DOM element” error.

    Cause: Keeping the script in the head and rendering on DOMContentLoaded is a viable option. However, if you retain the script in the head in this case, the document element will not be available when the script is launched.

    Cause:

    Keeping the script in the head and rendering on DOMContentLoaded is a viable option. However, if you retain the script in the head in this case, the document element will not be available when the script is launched. This is the reason why you’re getting the error: “_registerComponent(…): Target container is not a DOM element”.

    Solution:

    First of all, your script should be placed at the bottom of the body, and the root component should be displayed to a div before it, as seen below:

    <html>
<head>
</head>
<body>
<div id="root"></div>
<script src="/bundle.js"></script>
</body>
</html>

    Then let’s order in the bundle.js as below:

    React.render(<App />, document.getElementById('root'));

    In this post, I’ll give you one more piece of advise. Unless you always render to a nested div instead of the body, the 3rd party code ( for example browser plugins, Google Font Loader,…) can alter the DOM node’s body when React does not anticipate it, resulting in strange issues that are difficult to track down and fix.

    I hope that my solutions will be useful for you to solve your “_registerComponent(…): Target container is not a DOM element” error.

    Cause: After looking over your program, I discovered that instead of a JS file, your script tag links to an HTML file. This is why the warning message “Uncaught SyntaxError: Unexpected token ‘<‘ ” appears.

    Solution: Let’s check that any script tags you’re using point to a valid path and ensure that the names of your files are written in lowercase letters. The issue may occur if the file name contains capital letters or uncommon characters. If you follow the steps outlined above, the issue you’re having will be resolved effectively.

    The cause: The error can occur due to the following reasons: Saving a python list of numpy arrays that used np.save and then it is loaded with np.load. Therefore, imdb.load_data didn’t allow pickle.

    Solution: You should do this way to compel imdb.load_data to permit pickle.

    Change:

    (train_data, train_labels), (test_data, test_labels) = imdb.load_data(num_words=10000)

    into:

    import numpy as np
# save np.load
np_load_old = np.load

# modify the default parameters of np.load
np.load = lambda *a,**k: np_load_old(*a, allow_pickle=True, **k)

# call load_data with allow_pickle implicitly set to true
(train_data, train_labels), (test_data, test_labels) = imdb.load_data(num_words=10000)

# restore np.load for future normal usage
np.load = np_load_old

    Solution:  No need to bother about parsing.

    Maybe you just check in Chrome’s console:

    new Object().toString() 
// "[object Object]" 

JSON.parse(new Object()) 
// Uncaught SyntaxError: Unexpected token o in JSON at position 1 

JSON.parse("[object Object]")
