Minimal Reproductible Example (MRE)

request->send(LittleFS, "/index.htm", String(), false, processor);

I confirm that:

• I have read the documentation.
• I have searched for similar discussions.
• I have searched for similar issues.
• I have looked at the examples.
• I have upgraded to the lasted version of ESPAsyncWebServer (and AsyncTCP for ESP32).
