This problem is caused by the encoding problem of mongodb and the writing problem of the
.envfile. The first is the encoding problem of mogoddb. You only need to find theencoding.jsfile in/usr/local/learninglocker/current/xapi/node_modules/mongodb-connection-string-url/node_modules/whatwg-url/libin the xapi file and add const to it{ TextEncoder, TextDecoder } = require("util"); code.Then change the mongodb link in the .env file to
MONGO_URL=mongodb://localhost:27017/learninglocker_v2Make sure your node -v is 10, and xapi needs to be 6.0, not 7.0. Because the node used in 7.0 is version 16+.
By the way. It is best to use Ubuntu18 for installation. For Ubuntu20+, you need to modify "@google-cloud/pubsub": "^0.16.1" in
package.jsin webapp to 0.32.1.
