Images in Past Templates Fail to Load

[hiroshimuto9]

1. Problem Overview

When using the react-email-editor visual editor, images in previously created templates fail to load. The following types of image URLs return errors when accessed:

• https://assets.unlayer.com/stock-templates/xxxx
• https://assets.unlayer.com/projects/0/xxxx

This issue prevents past templates from being displayed correctly, making it difficult to edit or reuse them.

2. Detailed Explanation

Environment

• react-email-editor version: 1.7.11 (released on 2024-06-27)

Error Details

When accessing the image URLs directly in a browser, the following error messages appear:

Error Type 1:

<Error data-google-analytics-opt-out="">
<Code/>
<Message/>
<RequestId>xxxx</RequestId>
<HostId>{host-id}</HostId>
<LambdaGeneratedError>true</LambdaGeneratedError>
</Error>

Error Type 2:

<Error data-google-analytics-opt-out="">
<Code>BandwidthLimitExceeded</Code>
<Message>This asset is no longer accessible due to bandwidth limits for anonymous usage. To upload assets that remain accessible in the future, please create a project.</Message>
<RequestId>xxxxx</RequestId>
<HostId>{host-id}</HostId>
<LambdaGeneratedError>true</LambdaGeneratedError>
</Error>

Error Conditions:

Occurrence: The issue arises when attempting to load images included in templates created in the past.
Result: Images fail to load, either showing a 404 or 403 error in the browser.

3. Possible Cause

The error type 2 message indicates that the image assets are no longer accessible due to bandwidth limits imposed on anonymous usage. This suggests that Unlayer's service restricts access to image resources once a certain bandwidth threshold is exceeded.

4. Expected Behavior

Previously created templates should load images correctly, and their associated resources should remain accessible for:

• Editing
• Previewing
• Reuse in new templates

5. Additional Information

I have already contacted Unlayer's support team regarding this issue. If anyone else has encountered a similar problem and identified the root cause or a solution, I would greatly appreciate it if you could share your findings here.
