presignUrl() has moved to `@remotion/lambda-client`. Please

Error message

presignUrl() has moved to `@remotion/lambda-client`. Please import it from there.

What it means

In Remotion v5 (when NoReactInternals.ENABLE_V5_BREAKING_CHANGES is true), presignUrl() is no longer a working function exported from @remotion/lambda. It is replaced by a throwing stub directing users to import it from @remotion/lambda-client. This is part of the v5 package split that moves client-side rendering APIs into their own package.

Solutions

Import presignUrl from @remotion/lambda-client instead of @remotion/lambda.
Install @remotion/lambda-client if needed.
Update all other moved exports (renderMediaOnLambda, getRenderProgress, renderStillOnLambda, getSites) to the new package as well.

Example fix

// before
import {presignUrl} from '@remotion/lambda';

// after
import {presignUrl} from '@remotion/lambda-client';

Defensive patterns

Strategy: validation

Validate before calling

function assertLambdaClientImport(sourceModule: string, fnName: string): void {
  if (sourceModule === '@remotion/lambda' && NoReactInternals.ENABLE_V5_BREAKING_CHANGES) {
    throw new Error(
      `${fnName} must be imported from @remotion/lambda-client in v5.`
    );
  }
}

Prevention

When upgrading to v5, move presignUrl to @remotion/lambda-client.
Grep your codebase for presignUrl imports from @remotion/lambda after a major bump.
Follow the v5 migration guide for the complete list of moved exports.

When it happens

Trigger: Importing and calling presignUrl() from @remotion/lambda in a Remotion v5 codebase where ENABLE_V5_BREAKING_CHANGES is enabled.

Common situations: Upgrading from v4 to v5; generating presigned S3 URLs for render output using the old import path.
