Failing at connection after running npm install

[vladpap31]

I have a piece of code that connects to Redshift and runs a query. The code worked until I re-deployed today without changing anything in the functionality or the npm version. Note that every time I deploy the code, it installs all the npm packages before archiving.

In package.json I have "pg": "^7.4.1" as the dependency.

The error I am constantly getting is:

AssertionError: false == true

Anyone have a clue on what is causing this? Thanks!

I had this exact issue as well. It took our site down in production as we spun up new servers because the ^ character in your package.json means to load in the most recent minor version package, and since 7.4.2 is new as of 4 hrs ago it loaded that package in. I had to remove the ^ from my dependency so that it would lock in the previous version.

Edit: If someone with more knowledge than me things this is an pretty easy fix, let me know and I'll take a crack at trying to fix it.

@vitaly-t Note, that this issue appears to also impact pg-promise@8.4.1

[vitaly-t]

@vladpap31 Please tells us what versions of Node.js and PostgreSQL are you using.

Encountered the same issue 5 minutes ago.

Node: v10,
Postgres: 10.3

@larsthorup Thank you for pinging me on this. I have reverted pg-promise in version 8.4.2 to the previous version of the driver.

[vladpap31]

I am using Node 6.10 and the database is Amazon Redshift which is based off of PostgreSQL 8.0.2

[vitaly-t]

Ok, so it is fair to say at this point that the issue is irrelevant of the Node.js or PostgreSQL versions. It was a generic-type break in connectivity, caused by one of these commits:

• 5d32be4#diff-259dec4414a400a6e895f16ff1d0ca3b
• 4905471#diff-259dec4414a400a6e895f16ff1d0ca3b

I also ran into this Node 8.11.1

[mouf13]

Same result here since yesterday : Node 8.11.1, postgresql 9.4.6.
I'm using the lib through https://github.com/strongloop/loopback-connector-postgresql which use "pg": "^7.0.0"
To make my projects works again, i temporary set the pg version to "7.4.1" in my package-lock.json for the loopback-connector-postgresql
then i installed "pg-types"

[matthiasak]

did some sleuthing before I even saw this thread - fix here #1638

[etw3gh]

had to roll back to pg@6.4.2

[matthiasak]

For anyone needing to move forward, rolling back to 7.4.1 should work.

I had the same issue for anything >7
