I am using the Heimdall container within Synology Docker. It had been working just fine, but then I downloaded the latest release last night and updated the image. Now, I am getting HTTP 500 Errors when I try to go to the page, and the Heimdall error log shows:
In PackageManifest.php line 168:
- The /var/www/localhost/heimdall/bootstrap/cache directory must be present and writable.*
I tried mapping a volume to that directory, but that did not seem to work.
What might I be missing?
