 If the Sitecore Content Management instance can be accessed by multiple host names, you need to add AllowedCorsOriginsGroup for each site to the Identity Server configuration. This will enable the users for each site to be able to log in to the Sitecore shell using the Identity Server. The AllowedCorsOriginsGroup element defines a group of URIs that are allowed to make cross-origin requests to the Identity Server. You can use multiple subnodes to define more than one URI, or you can use the | symbol to separate URIs within a node. You can also use the {AllowedCorsOrigin} template to simplify the configuration. When you use that template, all origins (hosts) are notified about the sign-out1. References:

A placeholder key is a unique identifier that is used to refer to a specific placeholder in the presentation details of an item. A placeholder key is defined in the placeholder settings item that is linked to a rendering or a sublayout. A placeholder key can also be defined in the code or markup of a component. A placeholder key can be static or dynamic. A static placeholder key has a fixed value, such as /main. A dynamic placeholder key has a variable value, such as /main-{GUID}, where {GUID} is replaced by a unique identifier at runtime. Dynamic placeholders allow multiple instances of the same component to be added to a placeholder without conflicts. References:

 The sitecore.json file is the project configuration file that contains several properties, including a modules property that references the relevant Sitecore Content Serialization modules. If the path of a specific module file is not set in the modules property, the SCS system will not be able to locate and access the module file, which contains the items to be serialized. Therefore, the paths and related items included in the module will not be serialized when you run a push or pull command. This can lead to missing or inconsistent data between the Sitecore instance and the file system. References:
