Hey, thanks for the report. This error usually shows up when the request to the server goes over the 50 MB limit. The two most common causes are:

  1. HTTP/2 is disabled
    If you have the Disable HTTP/2 setting enabled (Settings > search “HTTP/2”), the data gets encoded less efficiently and ends up about twice as large. Please check that setting, and if it’s on, try turning it off.

  2. Large files in the project
    A 93 MB folder isn’t small. If it contains node_modules, binaries, or other big files, they can get pulled into the context. Try this:

  • Create a .cursorignore file in the project root and add heavy directories there, similar to .gitignore
  • For a quick test, open an empty folder and send “Hey”. If that works, the issue is in your project contents.

Also, please check if you have any Skills set in Cursor Settings. You said you don’t, but just to be safe, this is the most common reason for this error: Appendd data exceeds maximum size of 52428800 bytes

Let me know what you find.
