So, you are trying to use the Netlify Large Media feature and it isn’t working as expected. Where do you begin troubleshooting?
Well, we’re happy to help. Our Large Media plugin has several requirements to work correctly and those are listed here.
The first two requirements are:
- access to a Netlify account with permissions for this site
- the site is deployed via a tracked git repo (not manual deployments)
Netlify Large Media is built using Git Large File Storage (LFS). This means, if you aren’t using git, Netlify Large Media won’t work.
Third, much of what follows involves using
git on the command-line interface (or CLI). If you don’t know how to use
git via the CLI, please research that first before proceeding with the rest of this topic.
So, if you can log into Netlify and you are using
git on the CLI, what’s next?
Next, we will check to see if Large Media is installed. Do to this, run the following command (in the base directory of the
Then you what see in your command line should look similar to this:
$ netlify lm:info ✔ Checking Git version [2.20.1] ✔ Checking Git LFS version [2.7.0] ✔ Checking Git LFS filters ✔ Checking Netlify's Git Credentials version [0.1.8]
If you don’t see results similar to those above (your versions could be newer for example - which is expected), then there is something missing.
To resolve the issue, you will need to resolve the missing requirements. Those are:
- Git LFS version 2.5.1 or above, installed on your local machine. You can run
git lfs versionin your terminal to see if you have a valid version installed. If not, follow the installation instructions on the Git LFS website.
- Netlify CLI version 3.8.0 or above. Refer to our CLI docs for information on installation, authentication, and linking your local repository clone to your Netlify site.
Hmmm. Well, if all the requirements are met, it is time to check the details.
First, confirm that all the required versions are correct using this command, again, in the base directory of the git repo:
If that command shows versions equal to or newer than the required versions, now it is time to check the following files (again, they are found in the repo base directory):
In these files, look for common issues. If .gitattributes is empty, for example, the files are not being tracked by Git LFS. The solution would be to add files for tracking like so:
git lfs track <filename-or-filenames-here>
There are more details about this in our documentation here.
For the file
.lfsconfig, check to see if the URL in that file ends with
netlify.com/.netlify/large-media. Often people use another LFS provider like Github before switching to Netlify Large Media. Because of this, the previous LFS provider’s URL can be in
.lfsconfig instead of Netlify’s.
.gitignore? Well, one common scenario is that large media files are being ignored here because, possibly, they previously were not being tracked by git. If so, then removing the .gitignore rules which ignore those files can be the solution!
When your Git LFS service isn’t Large Media, whatever authentication you are using for your Git host (GitLab, GitHub, Bitbucket) is also used for Git LFS. However, when you move to Large Media, for any Git LFS tracked files, now Netlify’s authentication is used.
For that authentication to work something called the “Netlify Git credential helper” is installed. This is installed to the user’s home directory. Here are example locations on Linux and MacOS respectively:
You can tell if Git is configured to use the helper by checking with the command
git config -l. For example, here is me testing it below:
$ git config -l | grep netlify include.path=/home/username/.config/netlify/helper/git-config credential.helper=netlify lfs.https://a1ce8601-a525-4e47-b147-29e241fe546e.netlify.app/.netlify/large-media.access=basic
Above, we see it is working. If it isn’t working for you, you can install it manually.
To install it manually, first find the location of the file (which was
/home/username/.config/netlify/helper/git-config in my case). Then add these two lines to
[include] path = /home/username/.config/netlify/helper/git-config
Of course, you will need to use the correct path for where the helper was installed for you. After you save the file with those changes running
git config -l again should show the helper being used.
You should confirm that the shell helper is installed as well. When you first run
netlify lm:setup, the following is added to your
.bashrc (if your shell is
# The next line updates PATH for Netlify's Git Credential Helper. if [ -f '/home/username/.config/netlify/helper/path.bash.inc' ]; then source '/home/username/.config/netlify/helper/path.bash.inc'; fi
On MacOS, the line might look like this (the line added has evolved and this is an older example below):
# Netlify Large Media . /Users/username/.netlify/helper/path.bash.inc
So, if it is missing, how do you fix it? You need the following details to resolve this issue:
- the path were the credential helper is found
- the configuration file for the shell you are using
Using that information above, you then need to add the correct command to load the correct helper for your shell into the correct shell configuration file. If you have any questions about how to do this, we need the following details:
- the path were the credential helper is found (same as above)
- what operating system you are using
- what shell you are using
If you tell us those three details, we should be able to help you get the credential helper working in your shell environment.
Just because you are using Large Media doesn’t mean that anything else about deploying has changed.
Always, for any deploy at Netlify, any file you want to deploy must be found in the site’s publish directory when the build is finished. Only those files become part of the deployed site.
If you have files and they are not placed in the publish directory, you can access them during the build but only the files in the publish directory become part of the deployed site.
The same is true of Large Media. Just putting files into the repo - doesn’t magically publish them to the site at Netlify. They are only published if they are part of a deploy and, again, only if the files are placed somewhere in the publish directory.
The second most common cause is that the files simply don’t exist in the Large Media Git LFS service yet.
This happens because your Git client thinks the Git LFS service already has the files (meaning that the Git client doesn’t “know” that the Git LFS service changed). If the files are not modified, Git has no reason to upload them to Git LFS again (because it doesn’t send unchanged files). The end result is that the files exist for you locally but not at Large Media.
The solution is to force Git to send the files to Large Media (and this works for any Git LFS service). You can do so in your repo directory using this command below:
git lfs push --all origin
In many cases, this fixes Large Media assets not working. Also, you don’t even need a new deploy with this fix. The
push alone should simply make the data available in Large Media and the site will start working. (If not do try a new deploy but, again, in most cases that won’t be required.)
