I am getting the following error when attempting to initialize the server:

error: Error occured during reporter init Error: options contain values that does not match the defined full root schema. schema validation errors: rootOptions.store.provider should be equal to one of the allowed values. allowed values: ["memory"]

I am probably understanding this incorrectly but isn't it referring to the template store? In the documentation (https://jsreport.net/learn/template-stores) it states that template stores default to "fs".

In my config file I am finding the error being associated to

{  
    ...
    "store": {
        "provider":"fs"
    },
    ...
}

When I remove this, it defaults to using memory

Here is my install instructions. I have installed this on 4 servers with no issues, and then I rebooted three of them which those no longer work properly. Its quite confusing. I might try a clean install.

install node.js

sudo curl -sL https://deb.nodesource.com/setup_8.x | sudo bash -
sudo apt-get install -y nodejs

install jsreport

cd /opt
sudo mkdir jsreport
sudo chown svc:dev jsreport
sudo chmod g+w jsreport
cd jsreport
mkdir logs
sudo mkdir /opt/.npm-global
sudo chown svc:dev /opt/.npm-global
sudo chmod g+w /opt/.npm-global
npm config set prefix '/opt/.npm-global'
export PATH=/opt/.npm-global/bin:$PATH
source ~/.profile
sudo npm i -g jsreport-cli
jsreport init

chrome dependencies

sudo apt-get install -y libgconf-2-4
sudo wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
sudo sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list'
sudo apt-get update
sudo apt-get install -y google-chrome-unstable fonts-ipafont-gothic fonts-wqy-zenhei fonts-thai-tlwg fonts-kacst --no-install-recommends
sudo rm /etc/apt/sources.list.d/google.list
node server.js

start the jsreport server manually on port 5488 (optional)

node server.js
--rootDirectory=<rootDirectory>
--configFile=<configFile>
--logger.file.filename=<logger>
--error.file.filename=<error>

Edit 1: Proper permissions in temporary folder with a reboot still causes the error.

Edit 2: Reboot clears temporary drive which deletes /tmp/jsreport/core/locations.json. I believe it is being caused my supervisord which is creating a location.json file that contains only the following:

{"/opt/jsreportdev/node_modules/":{"locations":[],"lastSync":1579548899228}}

Edit 3: On my server node server.js only works with parameters after I have initially ran "node server.js" by its self first (and killed it). So running the following commands in the exact order (after reboot) causes jsreport to not throw the original error

node server.js
<kill it after it reports "init: reporter initialized">
node server.js
--rootDirectory=<rootDirectory>
--configFile=<configFile>
--logger.file.filename=<logger>
--error.file.filename=<error>

After that point I can run node server.js with parameters whenever I want and there are no issues. Once I remove "/tmp/jsreport/" and try to run it with the parameters, it fails with the original error. To get it working again I have to delete "/tmp/jsreport/" again (since I ran node server.js with parameters and it created a bad file), and then run "node server.js"

In the meantime, you can disable the extension locations cache in locations.json

node server.js --useExtensionsLocationCache=false
