403 error in Media Librairy with Google cloud storage

We use the @strapi-community/strapi-provider-upload-google-cloud-storage - npm plugin to store our images on google cloud storage. Uploading works. However, viewing does not work on some screens.
On the “Media Library” screen, the images are not displayed: the urls generated to display the images return a 403 error. However, if I remove the “updatedAt” parameter from the url, it works. And when I’m editing content, the image is displayed correctly (and the url generated doesn’t contain the “updatedAt” parameter.
Thanks for your help
