Convert multiple images to pdf

Hi there, dear Makers!

I am building automation that should assemble one PDF from multiple JPGs. For this task I choose

Everything seemed to be very simple: GDrive “Watch Files in a folder”, aggregation of links into a single string, separated with commas, a task to, and it worked. Just one time, and then - the same error (please look at the upper branch).

In case of this error, recommended uploading files to their storage first, so I did and broke my head with that wall: instead of one operation with bundles (each bundle for each file), I have a separate operation for each file (and the same situation if I use “Get share link” module.

I can not understand, how to aggregate all links to uploaded files into one array to create text with those links, separated with commas.

Does anybody solved this problem? Not necesserily with

Thank you for your attention and help!

Have you tried CloudConvert?


Just tried, and it worked! Thank you. But I still can not understand why it didn’t worked in my case, because the problem was BEFORE the pdfco module:

The trigger module was giving one operation with bundles, but download module was giving separate operation per each file download, so I could not aggregate them to array. But here it works … Can you please explain why?

And moret:
1)in aggregator there is 1st module set as a source:
2) Those target structure type … Where it came from?

Target structure type is when you are aggregating to a future module’s field for “mapping” purposes.

Every result (item/record) from a search module will output a bundle. To “combine” them into a single structure, you’ll need to use an aggregator of some sort.

Aggregators are modules that accumulate multiple bundles into one single bundle. An example of a commonly-used aggregator module is the Array aggregator module.

Hello Kaidano,

It seems like you’re working on automating the conversion of multiple images to PDF. Based on the error review, it appears that the files in your Google Drive folder haven’t been set with the file permission “Anyone with a link” to make them public. To resolve this issue, please set the permission of your Google Drive folder to “Anyone with a link” and then run the scenario again. By doing so, you should no longer encounter this error.

I hope this information is helpful to you. Thank you!
