Hyperledger Composer Failed to load connector module composer-connector-undefined for connection type undefined

}

I used the following commands to update my environment:

npm install -g composer-cli@next
npm install -g composer-rest-server@next
npm install -g generator-hyperledger-composer@next

I am getting this error:

Connection fails: Error: Failed to load connector module "composer-connector-undefined" for connection type "undefined".

Hey.

First, make sure that you are extending from the right docker image. Your docker file should look like this:

 FROM hyperledger/composer-rest-server:0.17.1
RUN npm install --production loopback-connector-mongodb passport-github && \
    npm cache clean --force && \
    ln -s node_modules .node_modules

If this is correct, then run these commands in the Fabric folder:

./teardownFabric.sh
export FABRIC_VERSION=hlfv11
./download.sh
./startFabric.sh

And if this also does not work, then reset Composer:

1. cd ~/lib/node_modules/composer-cli/
2. npm uninstall -g composer-cli
3. nvm install --lts
4. nvm use --lts
5. npm install -g composer-cli
