@little_grasshopper I’ve just pushed a new version of Hops (0.15.2) which now has an environment variable which you can configure to increase the request body size limit. You can now create an environment variable called RHINO_COMPUTE_MAX_REQUEST_SIZE which sets the maximum allowed size of any HTTP request body in bytes. The default value is set to 52428800 bytes (approx. 50mb). Try downloading this latest version and then setting a larger request size limit via the environment variable and let us know if that fixes your issue.
