contentblocks | Create simple editable CMS content blocks | Content Management System library

I have an useEffect hook which will do an axios get api request and store in an useState

I'm making a small CMS system in React and I have a form where users can use the Draft.js editor along with some other fields. For the question in mind, let's focus on the edit form.

The code for the editor looks like this:

I want to initialize my Editor state with a html markup but im getting this error

I'm trying to create a text editor using Draft.js, and I want it to be initiated with some content. The content is coming from a rest API that I have also created, but I am having some trouble with getting it to work. The editor itself works fine, but when I try to initiate it with the content it no longer works.

The way I'm trying to achieve this is by creating the editorState with createWithContent(), but I get the error:

TypeError: Cannot read property 'getSelection' of undefined.

I believe that it might be that the function that's using the 'getSelection' function is trying to access the editorState before its created, however, I'm not sure how to fix it.

This is my editor Class:

My goal: Have my Editor pre-populated with some default text and immutable entities. The text portions that would be made entities would be strings that match to a list ({{ immutable1 }}, {{ immutable2 }}, etc...). If a person types in a string in the editor that matches the list of pre-defined tokens then that string that they just typed immediately gets decorated and set as an immutable entity.

Problem: When the default text that gets pre-populated into the editor contains tokens in more than one block then it breaks and seems to add tokens from the last block into the first block.

I'm populating the Editor with an initial state this way:

I am working on a SilverStripe project. In my project, I am adding components to the GridField dynamically. Actually, I am trying to replace the existing components. Since there is no replace method, I have to remove the existing components and add the new components.

Following is my code

So this question has been asked several times and I see similar answers across SO and other question sites. The answers always seem to be either put Jackson dependencies in the class path or make sure that POJO classes have public getters(which I have tried but cant shake this error message off). I have a Spring Boot app hooked up to a MySQL db, I have little to no configuration because I wanted to see how far spring boot can auto config. I have a couple of spring boot starters in pom.xml, I assume they would handle the dependencies? When I test request path I get stacktrace.
