Facing the same issue

I ended up combining the error and json formats. Not great though

Hi @paul-uz , the above issue was resolved for me. Previously I was logging error object in error key. Now instead of error key rename it to err works
logger.error(msg, { error: ErrorObj });
Converting the above to below works
logger.error(msg, { err: ErrorObj });

tried using this workaround, but it didn't fix the issue - anytime I nest an error w/additional data it has an issue

I have also tried:

logger.error(msg, error, {details})
logger.error(msg, {details}, error)

The only way error is successfully printed is if i only pass the err object in like
logger.error(msg, error)
