Better diagnostic for wrong accessToken

[nataraj-hates-MS-for-stealing-github]

Hi! Below goes an original message about my problem.

I've managed to solve the problem. The cause of the problem described below was wrong accessToken.

It is just pure luck, I've found the solution, I've doublecheck everything, and found that token is copy-pasted in wrong way.

It would be nice to have better diagnostic for accessToken problem, that will allow to narrow down the possible source of the problem. So I did not have to check just everything...

Hi! I've been trying to setup dimension on current Debian Stable (Debian 11 aka Bullseye), following instruction
https://github.com/turt2live/matrix-dimension/blob/master/docs/installing.md

But when I reach

1
NODE_ENV=production npm run start:app
it finishes with error:

npm ERR! code 1
npm ERR! path /srv/dimension/app
npm ERR! command failed
npm ERR! command sh -c npm run-script build && node build/app/index.js

npm ERR! A complete log of this run can be found in:
npm ERR!     /home/nataraj/.npm/_logs/2022-08-16T13_28_02_005Z-debug.log

When I look in the log file, it says:

I am no node.js developer, I have no idea what all this mean...

Can you please help me make it up and running?
