Reproduction Steps

Version used

"@apollo/client": "^3.7.10",
"@apollo/federation-internals": "^2.3.5",
"@apollo/gateway": "^2.3.5",
"@apollo/server": "^4.5.0",
"@apollo/subgraph": "^2.3.5",

I've tried with different version, 2.2.1 to 2.3.5.
Thanks for your help

This error happens if the schema has a definition for the @tag directive that differs from what is expected by the federation specification linked in the schema. See this comment too.

It's difficult to help more without some additional details, but essentially the schema provided to the buildSubgraphSchema method has some definition for directive @tag and that definition should probably be removed (since buildSubgraphSchema will add it back with the exact definition it expects).

With 2.2.3 works perfectly.

This appears to be a package version issue. @nmacherey are you still experiencing this / did you find a resolution? If not, can you share the output of:
npm ls @apollo/subgraph

Also I can't think of a reason why you should have @apollo/federation-internals specified as a dependency in your project. Are you using it for something?

Related issue in nestjs, where the solution seems to be "just upgrade":

Closing as stale (and possibly solved). Happy to reopen if the issue persists and we get a reproduction.
