I get this error after flashing twrp using sp flash tool; please download recovery image with correct signature error 
However, if i flash back the stock recovery, it fixes it. What can i do to successfully flash twrp with spft with no errors.

you're to unlock bootloader and disable dm_verity by flashing empty vbmeta before attempting to flash any custom image on such a device

I don't think it is possible to achieve that without bootloader unlock.

unlocking bootloader is a compulsory step if you intend to flash custom images on the device
