Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires ibexa/connector-anthropic 5.0.5 -> satisfiable by ibexa/connector-anthropic[v5.0.5]. - ibexa/connector-anthropic v5.0.5 requires league/uri ^6.8 -> found league/uri[6.8.0] but the package is fixed to 7.8.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command. Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
