Dynamic Input: Ignoring error and continue process when file does not eixst

I have a workflow which takes input from the users runs through a formula and into a Dynamic Input tool to pull in files. Sometimes 1 of those files do not exist and the Dynamic Input file will error and the workflow will stop. I need the workflow to continue. I searched many issues in the community pages but the issues I've found are not the same. Since I am providing the Dynamic Input with the full path to a file which doesn't exist, it just errors and doesn't try to open default template file. Easy way to reproduce would be to have a formula tool create a full path to a file which does not exist feed a Dynamic Input tool with a good template.

Hi @AdamTX

You can use a variation on this technique.

User List contains the list of files. The directory tool reads the list of files from path the user has entered or a fixed path, if it's always the same. Join both on full path. Only the existing files will be passed on the dynamic input tool so it won't error on non-existant files

@AdamTX,

What's the desired output from the dynamic input tool if the file path is bad? I think you can get around the issue you are describing with a batch macro, but I'd have to know more about what you'd expect it to do.

If file path is bad, I don't want a failure to trigger and just pass no data - maybe load a blank template file is needed and finish processing. I don't even need a warning message telling me the file wasn't there. I can tell if data is missing.
