Panic when running `toolkit deploy-ocr3-jobspecs` during `setup.sh` (`unsupported operation in loop mode`)

[MohammadJamali]

When running the setup.sh script, the following command fails with a panic:

go run main.go toolkit deploy-ocr3-jobspecs \
  --ethurl=http://localhost:8544 \
  --accountkey=348ce564d427a3311b6536bbcff9390d69395b06ed6c486954e971d960fe8709 \
  --chainid=1337 \
  --p2pport=6691

Observed Error:

panic: not available in loop mode: unsupported operation

exit status 2

It looks like there’s a version mismatch between Chainlink and the way Keystone deploys tasks.

To fix it, you must set export FEATURE_OFFCHAIN_REPORTING2=true before running the node. However, once you do that, you will get another error:

chainlink/config_general.go:275  logger=RunNode version=2.27.0@1d467cc 
config validation failed: invalid environment: 2 errors:
 - environment variable FEATURE_OFFCHAIN_REPORTING2 must not be set: unsupported with config v2
 - environment variable FEATURE_OFFCHAIN_REPORTING must not be set: unsupported with config v2
