Building ENV mongodb string with CA_CERT

I am very close to getting my mongodb database connected in the App Platform. I built up the env value like this


I get this error Error: ENOENT: no such file or directory, open ‘-----BEGIN CERTIFICATE-----’ which makes me think there is another thing like tlsCAFile but to point to a string instead, as the App Platform is giving me this CA_CERT through the ENV. I think it will work once I get this.

Hi there,

Indeed, in order to connect to MongoDB, you need to specify the location of the certificate file rather than passing the certificate as a string to the connection string.

One way to do that is to create the file in your app’s code, before initializing the MongoDB connection. Here is an example for MongoDB:

fs.writeFileSync(path.resolve(__dirname, ""), process.env.CA_CERT)

Hope that this helps!
