I try a lot on Web Client in SAP B1 10.0 PL02 (SQL version) but not success. I deep down into the issue via code. I know that Web Client is developed by using NodeJS technology and I test it by write log.
The root cause of error is from variable is undefined from this coding line
const url = new URL("http://"+process.env.b1_jdbc_url.substr("jdbc:sap://".length));
And so, First of all, I open web client from SAP B1 itself and it error as picture below

And so, I open Web Client folder to modify code to show log and run it
