TL;DR

• Verify the custom plan directory configuration to ensure it allows writing nested files.

Guidance

• Check the permissions and access control settings for the custom plan directory to ensure that extensions have the necessary rights to write files.
• Review the directory structure and path settings to confirm that the extension is attempting to write files to the correct location within the custom plan directory.
• Test writing files to the root of the custom plan directory to isolate if the issue is specific to nested files.

Example

• No code snippet is provided as the issue does not include specific code or technical details.

Notes

• The solution may depend on the specific configuration and implementation of the custom plan directory and extensions.

Recommendation

• Apply workaround: Modify the custom plan directory configuration to explicitly allow writing nested files, if possible, to resolve the issue.
