Problems with Ubuntu Firefox 86.0 with ERC upload and Binding creation

[Fmazin]

On this version two problems accrue:

1. The workspaces are uploaded correctly but the user is not correctly directed to the Create ERC page.
   This happens only to some workspaces and the size of the file seems to be the deciding factor. On the dev build you get this error message.
   

When you do this on the production build the loading Message just stops at 80% and nothing happens. But again you can checkout the the creation page if you enter the link to the creation page.

In the first case the console displays this error:

Response: Error: Network Error
    createError http://localhost/static/js/1.chunk.js:45678
    handleError http://localhost/static/js/1.chunk.js:45229

2. When creating a binding you can do all steps except the final add or save parameter operation. The reason for this is that the button does not become clickable.

The issue doesn't come up with Chrome or Opera.

This might be related to #190.

I tried to reproduce both errors:

1. I also encountered this problem. For it just happend sometimes, and not always. I got the same error, like @Fmazin. I implemented a further catch, so the website not crush. I do not know why this error occurs.

2. I could not reproduce this error. For me everything works fine on Ubuntu Firefox 86.0.

1. Sounds good. The error was frequent in my experience but not guaranteed.
2. Maybe it is my own setup then. I will try to get info on this.
