symfony/http-foundation incompatibility with Drupal 10

[davejenx]

Trying nz.co.fuzion.omnipaymultiprocessor version 3.21 with Civi 5.65.2 on Drupal 10.1.6, getting the following error:

PHP Fatal error: Declaration of Symfony\Component\HttpFoundation\ResponseHeaderBag::all() must be compatible with Symfony\Component\HttpFoundation\HeaderBag::all(?string $key = null): array in .../nz.co.fuzion.omnipaymultiprocessor-3.21/vendor/symfony/http-foundation/ResponseHeaderBag.php on line 93

The extension's composer.lock has symfony/http-foundation version "4.4.x-dev", which comes as a dependency of:

• omnipay/common - require "symfony/http-foundation": "^2.1|^3|^4|^5|^6"
• omnipay/tests v3.1.1 - require-dev "symfony/http-foundation": "^3|^4"

The site's composer.lock has symfony/http-foundation version "v6.3.7", which comes as a dependency of, among others:

• drupal/core - "symfony/http-foundation": "^6.3"

So omnipay/tests seems to be the thing holding it back. The extension's composer.lock has various packages requiring omnipay/tests under require-dev (but none as non-dev require), including omnipay/common which specifies "omnipay/tests": "^4.1", which confusingly doesn't fit with the installed version, omnipay/tests v3.1.1 .

Has anyone got this working on D10?

Same issue here:
Fatal error: Declaration of Symfony\Component\HttpFoundation\ResponseHeaderBag::all() must be compatible with Symfony\Component\HttpFoundation\HeaderBag::all(?string $key = null): array in .../sites/default/files/civicrm/ext/nz.co.fuzion.omnipaymultiprocessor/vendor/symfony/http-foundation/ResponseHeaderBag.php on line 93
"omnipay/common", require "symfony/http-foundation": "^2.1|^3|^4|^5|^6"
"omnipay/common": "^3", require-dev "symfony/http-foundation": "^3|^4"

What is going on ?

Related, but on civi 5.69.5 and drupal 9.5.11

Declaration of Symfony\Component\HttpFoundation\JsonResponse::create($data = null, int $status = 200, array $headers = []) must be compatible with Symfony\Component\HttpFoundation\Response::create($content = '', $status = 200, $headers = []) in nz.co.fuzion.omnipaymultiprocessor/vendor/symfony/http-foundation/JsonResponse.php on line 73

Hi team I have solved a similar issue
AttributeBag::getName() must be compatible with Symfony\Component\HttpFoundation\Session\SessionBagInterface::getName()

Our solution was to identify which symfony library caused the issue from the above error message we can see this is symfony/http-foundation

Repeating steps here in case helpful for others.

I used

find $SITEROOT -name 'SessionBagInterface.php';
to identify that the clash was between the root vendor and vendor in this extension

composer why symfony/http-foundation
gives us which versions of this component might be acceptable in each location and we can find a common version and use composer (or edit composer.json) to set the version we want then use composer to upgrade to the correct version.

i.e. composer upgrade --dry-run -w and composer upgrade -w if that succeeds.
