I followed the steps to add a TanStackDevtools component and ran into two problems:\n\n1) A constant loop in vite with this error.  I fixed this by adding '@tanstack/devtools' to vite.config.ts optimizeDeps.exclude.\n```\n✘ [ERROR] No matching export in \"node_modules/.pnpm/solid-js@1.9.7/node_modules/solid-js/web/dist/dev.js\" for import \"setStyleProperty\"\n\n    node_modules/.pnpm/@tanstack+devtools@0.11.2_csstype@3.2.3_solid-js@1.9.7/node_modules/@tanstack/devtools/dist/devtools/4QORE6HP.js:4:102:\n      4 │ ...use, setAttribute, insert, memo, effect, className, setStyleProperty, addEventListener, style, template, classList } fro...\n        ╵                                                        ~~~~~~~~~~~~~~~~\n\n\n ERROR  7:46:47 AM [vite] (client) error while updating dependencies:                                                         07:46:47\nError: Build failed with 1 error:\nnode_modules/.pnpm/@tanstack+devtools@0.11.2_csstype@3.2.3_solid-js@1.9.7/node_modules/@tanstack/devtools/dist/devtools/4QORE6HP.js:4:102: ERROR: No matching export in \"node_modules/.pnpm/solid-js@1.9.7/node_modules/solid-js/web/dist/dev.js\" for import \"setStyleProperty\"\n    at failureErrorWithLog (/Users/andrew/GitHub/finalist/node_modules/.pnpm/esbuild@0.25.12/node_modules/esbuild/lib/main.js:1467:15)\n    at /Users/andrew/GitHub/finalist/node_modules/.pnpm/esbuild@0.25.12/node_modules/esbuild/lib/main.js:926:25\n    at /Users/andrew/GitHub/finalist/node_modules/.pnpm/esbuild@0.25.12/node_modules/esbuild/lib/main.js:1345:9\n    at process.processTicksAndRejections (node:internal/process/task_queues:104:5)\n```\n\n2) this runtime error that I have not been able to bypass:\n```\nSyntaxError: The requested module '/node_modules/.pnpm/dayjs@1.11.20/node_modules/dayjs/dayjs.min.js?v=559389e5' does not provide an export named 'default' (at tree.js?v=559389e5:6:8)\n```\nthe line it's pointing to is in @tanstack/devtools-ui/dist/esm/components/tree.js\n```\nimport dayjs from \"/node_modules/.pnpm/dayjs@1.11.20/node_modules/dayjs/dayjs.min.js?v=559389e5\";\n```\n\nI think it has to do with the tsconfig option `allowSyntheticDefaultImports` which I did not previously have set, but I tried adding it (and rerunning with `vite dev --force` to force it to rebuild) but that did not make it work.\n\nSorry, I'm going through the trouble of creating a bug report, I don't have the time to also create a minimal reproducible example.
