you updated the composer packages, right?

U01LE4BMBK7

quickfix:

git restore composer.lock
docker/sdk cli composer install

U01LE4BMBK7

had the same issue yesterday

U01LE4BMBK7

I think they want you to run

docker/sdk cli composer require filp/whoops

if you want to keep using the ErrorHandler plugins

U01BH6ZNS8H

Thank you Philipp, so should I just install filp/whoops with composer require filp/whoops

U01BH6ZNS8H

Yes I ran composer update as I was getting another error saying some Class not found.

U01BH6ZNS8H

Now I am getting below error: Exception
Could not find config key "CUSTOMER_PAGE:CUSTOMER_REMEMBER_ME_SECRET" in "Spryker\Shared\Config\Config"

U01LE4BMBK7

maybe you updated other packages as well and need to follow the changelog to update your project

U01LE4BMBK7

seems like this key was introduced in https://github.com/spryker-shop/customer-page/releases/tag/2.29.0

U01BH6ZNS8H

I ran composer update, now could you plz help how can I get this change added to my project

U01AZE27XGV

Even I am facing the same issue, any suggestions please

U01LE4BMBK7

maybe some other package got updated as well:
https://github.com/spryker-shop/customer-page/releases/tag/2.29.0

U01LE4BMBK7

you probably updated many packages..not sure if that's what you really want

U01LE4BMBK7

ideally just install filp/whoops and don't update all Spryker packages

U01AZE27XGV

I did install filp/whoops

U01LE4BMBK7

do you still have the logs how it was installed? check if any spryker packages was updated as well

U01LE4BMBK7

if so, reset your composer.lock and install filp/whoops like this:

docker/sdk cli composer require filp/whoops --no-scripts --no-update
docker/sdk cli composer update filp/whoops

U01AZE27XGV

version it is showing 2.9

U01LE4BMBK7

but check git diff composer.lock if you changed other Spryker packages accidentally

U01LE4BMBK7

I think the best is to reset your composer.lock and run

docker/sdk cli composer install
docker/sdk cli composer require filp/whoops --no-scripts --no-update
docker/sdk cli composer update filp/whoops

U01LE4BMBK7

if you see some downgrades when running docker/sdk cli composer install then you had Spryker packages updated before
