Bluetooth : BT Host Error on Esp32

[anmolaggarwal]

We are trying to communicate with the ESp32 over bluetooth and we are following a command and reply protocol. While communicating, we get an error on the serial monitor (shown in attachment). Although the SPP_WRITE_EVENT is complete, we don't get the reply on our mobile device.
However, the error occurs only in case of some specific commands and some devices. Switching to a different device eliminates the error. Could you please help us identify if this is a known issue and what it is about?
