This is because react-email/components didnt handle it correctly and fell back to client side rendering. This was outside of our try catch code, it was in the actual rendering. So it came back as status-ok. We bump versions to the latest version which does throw it. We also have to update the freestyle mock. Bun cannot handle these kinds of errors. they are treated as uncaught exceptions by it. So we switch to node. We also refactor some tests because the react-email components now return slightly different messages. --- apps/backend/src/lib/email-rendering.tsx | 5 +- .../endpoints/api/v1/email-themes.test.ts | 17 +- .../api/v1/emails/email-queue.test.ts | 34 +-- .../api/v1/internal/email-drafts.test.ts | 46 ++-- .../api/v1/internal/email-templates.test.ts | 25 +-- .../endpoints/api/v1/render-email.test.ts | 78 ++++++- docker/dependencies/freestyle-mock/Dockerfile | 199 +++++++++--------- 7 files changed, 243 insertions(+), 161 deletions(-) diff --git a/apps/backend/src/lib/email-rendering.tsx b/apps/backend/src/lib/email-rendering.tsx index af226ff34b..06664c4c68 100644 --- a/apps/backend/src/lib/email-rendering.tsx +++ b/apps/backend/src/lib/email-rendering.tsx @@ -1,7 +1,6 @@ import { executeJavascript, type ExecuteResult } from '@/lib/js-execution'; import { emptyEmailTheme } from '@stackframe/stack-shared/dist/helpers/emails'; -import { getNodeEnvironment } from '@stackframe/stack-shared/dist/utils/env'; -import { captureError, StackAssertionError } from '@stackframe/stack-shared/dist/utils/errors'; +import { StackAssertionError } from '@stackframe/stack-shared/dist/utils/errors'; import { bundleJavaScript } from '@stackframe/stack-shared/dist/utils/esbuild'; import { get, has } from '@stackframe/stack-shared/dist/utils/objects'; import { Result } from "@stackframe/stack-shared/dist/utils/results"; @@ -50,7 +49,7 @@ export function createTemplateComponentFromHtml(html: string) { const nodeModules = { "react-dom": "19.1.1", "react": "19.1.1", - "@react-email/components": "0.1.1", + "@react-email/components": "1.0.6", "arktype": "2.1.20", }; diff --git a/apps/e2e/tests/backend/endpoints/api/v1/email-themes.test.ts b/apps/e2e/tests/backend/endpoints/api/v1/email-themes.test.ts index 13effc0b07..771e72c2e7 100644 --- a/apps/e2e/tests/backend/endpoints/api/v1/email-themes.test.ts +++ b/apps/e2e/tests/backend/endpoints/api/v1/email-themes.test.ts @@ -411,7 +411,10 @@ describe("invalid JSX inputs", () => { } ); expect(response.status).toBe(400); - expect(response.body).toMatchInlineSnapshot("???"); + expect(response.body).toMatchObject({ + code: "EMAIL_RENDERING_ERROR", + }); + expect(response.body.error).toContain("Intentional error from theme"); }); it("should reject theme that does not export EmailTheme function", async ({ expect }) => { @@ -564,13 +567,11 @@ describe("invalid JSX inputs", () => { } ); expect(response.status).toBe(400); - expect(response.body).toMatchInlineSnapshot(` - { - "code": "EMAIL_RENDERING_ERROR", - "details": { "error": "{\\"message\\":\\"element.type is not a function.
