I am trying to summon a lightning bolt when a repeating command block detects an arrow on grass, but every time the command block runs it throws the error:
Failed to execute 'summon' on Arrow.
I'm on Minecraft Bedrock version 1.12.1.
Command:
/execute @e[type=arrow] ~ ~ ~ detect ~ ~-1 ~ grass 1 summon lightning_bolt

Currently, your command is executing at all arrows which are on a block of grass with a metadata of 1; typical grass blocks don't have a metadata of 1. In order to fix this, set the value of 1 to -1, resulting in:
The value of -1 tells Minecraft to ignore metadata instead of check for it.
