The solution for creating application pod experiencing developer password failure uses the variable DB_PASSWORD=test in the solution. From where did this variable name come ?

I tried doing describe on the postgresql pod and it shows variable name POSTGRESQL_PASSWORD and could not find mention of DB_PASSWORD variable.

Also in solution video for the lab exercise is from web console and there is no error shown in solution for developer user password failure for pod. However when I use the DB_PASSWORD solution it did work and the lab grading passed. 

TIA.

I got the answer to my question from where the DB_PASSWORD variable came from. It is from the db.js application code . Thanks to post by @HansVandeweghe which made me think in this direction. I must admit I am not a developer but trying to learn here. Used a bit of GROK AI to understand the code and also got it reviewed and got some new code with corrections in line 8 user mentioned twice. "const client = new Client({ host, user, database, user, password }); " The DB runs with developer user and test password whereas the code uses developer user and developer password. That is the issue and changing the variable value of DB_PASSWORD for the db.js code makes it connect with correct password and issue is fixed.

@Ravi_Shanker absolutely right :

I encountered the same issue. How can I find the variable named DB_PASSWORD? The error from 'oc logs' doesn't provide the name of this variable.

Also, where can I find the source code for this answer?
