[BUG] Long passages of text trigger unusual error message

[stockholmux]

Describe the bug
Paragraph codeblocks fail with very long text entry (tired pasting in the entire text of Moby Dick, several Mbs) -> Error message "Error running paragraph, please make sure you have the correct permission."

Expected behavior
Either the error message would be more exact (it has nothing to do with permissions) or limit the number of character allowed in the text box

Plugins

Thanks for reporting this, the dashboards server has a max_payload limit, and rejects if a request is too large. Will work on a fix
