(closed) Postman can't be opened properly

Question

I'm trying to open my newly installed Postman when an error occurs which says something like this:

**Could not open Postman**
Error: Migration: IndexedDB schema migration failed. IndexedDb was not upgraded succesfully after `dexie.open`.
Please try restarting the app. If the issue persists, please refer to http://go.pstmn.io/troubleshoot-could-not-open

As it says, the error really persists. The website above only provides suggestions like "reinstall the app" "upgrade the app", which are not really helpful. And as I dig into the Internet, it occurs to me that such error hardly happens (found nobody have the same question like me).

"IndexedDb" was mentioned in the error message, and I just know (from the Internet) that it's a nosql database provided by explorer. Maybe the problem can be solved by reinstalling the database, I guess?

Answer 1

Can you try just by deleting the “Postman” folder or renaming it to “Postman.old” from below two locations and then reinstall the latest version from here and see if that helps?

C:\Users\<user>\AppData\Local and C:\Users\<user>\AppData\Roaming

I tried it as I was facing the same issue and, it solved for me.

Answer 3

Go to installation folder of Postman:

C:\Users\Davoud\AppData\Local\Postman

delete the older version's folder. It fixed my problem. Actually I also deleted update.exe too.

Answer 4

I had a similar problem and found this description: https://github.com/postmanlabs/postman-app-support/issues/4897

Short answer is, delete the Postman configs directory at ~/.config/Postman (for Linux) and then try running again. This will delete any saved Postman data you have, but for a newly-installed instance that's not an issue.

Instead of deleting the whole Postman folder, just delete the IndexedDB folder in ~/.config/Postman. I got this error while performing an upgrade, and i cannot afford to remove the whole Postman Data – Apivorous

I faced a different error when starting postman. The disableGPU setting is set to undefined Not disabling GPU I also solved it by deleting ~/.config/Postman – Spermary

   -> C:\Users{user}\AppData\Local
   -> C:\Users{user}\AppData\Roaming\

3. Reinstall the postman.

4. It will be asked to log in, and login into the web.

5. All done.

This worked for my Windows 10 OS – Unequal

Answer 6

For Windows 10 - in my case, I have to:

• Open Task Manager and kill/end the Postman application.
• Go to %appdata% and search the "Postman" folder.
• Inside "Postman" folder, select the "Postman_Config" folder¹. Delete it.
• Try to open your Postman instance again.

---

¹ The "Postman_Config" folder contained (in my case) another folder called "0" and inside this folder, an "userconfigs.json" file - which only contained these characters:

{}

If you have additional information,please, make a copy of these files in order to have a backup - if needed.

Answer 9

I had a similar problem installing Postman when I was on a VPN (on Windows). It started up but then got a popup error saying "TypeError: Cannot read property 'id' of undefined," and a blank white screen afterwards. So I uninstalled it, deleted any Postman folders, turned off the VPN, and re-installed it with no problems! After it installed successfully, I was able to turn on my VPN and had no further issues.

For reference, I had these errors in my C:\Users\<user>\AppData\Roaming\Postman\logs\renderer-requester.log file

Answer 11

I had a similar issue while I used postman on fedora, I created a proxy directory and created a dummy certificate using openssl

step 1: check whether the directory exists ls -l ~/.config/Postman

step 2: create a proxy dir mkdir -p ~/.config/Postman/proxy

step 3: create a dummy certificate touch ~/.config/Postman/proxy/postman-proxy-ca.crt

step 4: sudo dnf install openssl

step 5:openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout ~/.config/Postman/proxy/postman-proxy-ca.key -out ~/.config/Postman/proxy/postman-proxy-ca.crt step 6: set permissions chmod 644 ~/.config/Postman/proxy/postman-proxy-ca.crt

now try to run postman....
