Error occured setting content: while opening app on appdesigner!!

Hi Everyone,

I am trying to open a .mlapp file on appdesigner but i am getting the below error:

Error occured setting content: Type Error:Failed to execute 'appendChild' on 'Node':Parameter 1 is not of type 'Node'.

The app used to run and when I opened the file after a few days i get the error stated above.

Any help would be greatly appreciated.

It also happens to me :c

Did you solve it?

[Kunal Khosla]

Yes. I solved it by removing spaces in my filename.app file. For Example function 1.mlapp wont work but function1.mlapp will work.

I am facing same issue but with normal .m files in matlab online. & my files already didn't use any spaces in filenames. I tried without _ but even that isn't solving this issue please help.

I have the exact same problem!

Is there really no solution?

I have been able to open all the files in the past but for some reason it has now suddenly stopped working.

Even if I create a completely new file, save it and then try to open it I get the same error.

There are no spaces in my file names.
