Deprecation: #89579 - ServiceChains require an array for excluded Service keys¶
The Service API within
ExtensionManagementUtility::findService() has a third argument called
$excludeServiceKeys which is used for skipping certain services when
using a chain.
The third argument could previously be a comma-separated list or an array. The argument now requires an array for consistency and performance reasons.
Handing in comma-separated value strings is deprecated and will be removed in TYPO3 v11.0.
Calling any of the methods above with a non-array as third argument will trigger a deprecation notice.
Any TYPO3 installation with custom extensions using the Service API directly. Extensions that ship a custom authentication provider are not affected.
Ensure to hand in an array as third argument.
