Can't get 'fabcar' javascript docker images to run - hyperledger-fabric

Question

I'm on Windows and have all the prerequisites described for Hyperledger. I'm following this tutorial: https://hyperledger-fabric.readthedocs.io/en/release-1.4/write_first_app.html. Inside my fabcar folder, I ran ./startFabcirc.sh javascript and it fails to run the docker containers. The message I get specifically is
Stopping for channel 'mychannel' with CLI timeout of '10' seconds and CLI delay of '3' seconds

Failed to generate orderer genesis block...
Do I need to set the private key it mentions at the beginning BYFN_CA1_PRIVATE_KEY variable is not set? Or do I need to specify a channel name as I've seen in other posts?
I can't find a configtx.yaml file in the /fabcar folder but can fine one in `/fabric-samples/config'. I still get the same error. Here is the file (note I removed the headers to remain in the 30k character limit for StackOverflow)

# Orderer Type: The orderer implementation to start.
# Available types are "solo" and "kafka".
OrdererType: solo
# Addresses used to be the list of orderer addresses that clients and peers

Addresses:
# - 127.0.0.1:7050
# Batch Timeout: The amount of time to wait before creating a batch.
BatchTimeout: 2s
# Batch Size: Controls the number of messages batched into a block.
# The orderer views messages opaquely, but typically, messages may
# be considered to be Fabric transactions. The 'batch' is the group
# of messages in the 'data' field of the block. Blocks will be a few kb
# larger than the batch size, when signatures, hashes, and other metadata
# is applied.
BatchSize:
# Max Message Count: The maximum number of messages to permit in a
# batch. No block will contain more than this number of messages.
MaxMessageCount: 500
# Absolute Max Bytes: The absolute maximum number of bytes allowed for
# the serialized messages in a batch. The maximum block size is this value
# plus the size of the associated metadata (usually a few KB depending
# upon the size of the signing identities). Any transaction larger than
# this value will be rejected by ordering. If the "kafka" OrdererType is
# selected, set 'message.max.bytes' and 'replica.fetch.max.bytes' on
# the Kafka brokers to a value that is larger than this one.
AbsoluteMaxBytes: 10 MB
# Preferred Max Bytes: The preferred maximum number of bytes allowed
# for the serialized messages in a batch. Roughly, this field may be considered
# the best effort maximum size of a batch. A batch will fill with messages
# until this size is reached (or the max message count, or batch timeout is
# exceeded). If adding a new message to the batch would cause the batch to
# exceed the preferred max bytes, then the current batch is closed and written
# to a block, and a new batch containing the new message is created. If a
# message larger than the preferred max bytes is received, then its batch
# will contain only that message. Because messages may be larger than
# preferred max bytes (up to AbsoluteMaxBytes), some batches may exceed
# the preferred max bytes, but will always contain exactly one transaction.
PreferredMaxBytes: 2 MB
# Max Channels is the maximum number of channels to allow on the ordering
# network. When set to 0, this implies no maximum number of channels.
MaxChannels: 0

Answer 1

You need to make sure that your FABRIC_CFG_PATH is set to the directory which contains configtx.yaml
Try running echo $FABRIC_CFG_PATH and if it doesnot point to the directory which contains configtx.yaml, you need to set it by the command export FABRIC_CFG_PATH=$PWD inside the directory where you have configtx.yaml
If this doesn't work then you have errors in configtx.yaml file. You need to post that in your question too.
