I’m struggling with the Server Action Download File.
I’m trying to download a PDF File with a button in a Server Connect Form.
My problem is that I get the source of the file (%PDF-1.4 %âãÏÓ 1 0 obj << …) instead of the file.
What am I missing?
Are you sure you followed the docs?
The first part yes, with the difference, that I use it with a dynamic file. It gets the path information from the database filtered by the POST variable.
For the second part I thought I could use POST instead of GET, that’s why I used Server Connect Form. Does it only work with a GET variable?
You need to use a direct link to your server action (using an anchor <a>) you cannot do it when posting a form.

Thanks for your help and clarification.

Same issue here with Server Action Download File.
I’m trying to download a File with a button using dynamic event to load serverconnect and pass the file name parameter (stored in a variable). On click I get the following response in the browser devtools- network
Request URL:http://localhost:3000/api/dwnldReport?filename=Dummy.pdf (copy-pasting this path in browser downloads the file successfully)
Request Method: GET
Status Code:200 OK
Preview/Response: %PDF-1.3 %ºß¬à 3 0 obj <</Type /Page…
Please advise.
You need to use a link (anchor) to call your download server action, not via a dynamic event.
Tried the following:
- Anchor Button > Link > api/dwnldReport/{{varDownloadReport.value}}
Code:
<a class="btn" href="api/dwnldReport/{{varDownloadReport.value}}">Anchor Button</a>
Response: {“status”:“404”,“message”:"/api/dwnldReport/%7B%7BvarDownloadReport.value%7D%7D not found."}
- Link > Link > api/dwnldReport/{{varDownloadReport.value}}
Code: <a href="api/dwnldReport/{{varDownloadReport.value}}">Your link title</a>
Response: {“status”:“404”,“message”:"/api/dwnldReport/%7B%7BvarDownloadReport.value%7D%7D not found."}
Well you need to use dynamic link for this (dynamic attributes > links > link ) to add dynamic values in the href.
The resulting code would be:
<a class="btn" dmx-bind:href="'api/dwnldReport/' + varDownloadReport.value">Anchor Button</a>
Tried as you said, got the same expression as you wrote:
<a class="btn" dmx-bind:href="'api/dwnldReport/' + varDownloadReport.value">Anchor Button</a>
Response:
{“status”:“404”,“message”:"/api/dwnldReport/Dummy.pdf not found."}
I have the following setup
Server connect config:

Browser Response:
What are you trying to do exactly? The anchor/link must point to the server action, not to the actual file.
Then in the server action you provide the link to this file.
I have a table with a list of people and their reports (pdf files) are uploaded in a folder inside the project. The filename is stored in the database. I am trying to give a link in the same table to download the report in front of each person’s name.
For this I have a serverconnect to get the filename from db and store it in a variable. Then another serverconnect for filedownload to be called when i click the download link and pass the filename stored in the variable to serverconnect for file download.
I see you want to pass it as a GET var and your route looks correct. So indeed this is the correct syntax:
<a class="btn" dmx-bind:href="'api/dwnldReport/' + varDownloadReport.value">Anchor Button</a>
and it should be working just fine.
What server model are you using?

Which is your real path to the file Dummy.pdf? Is it really under “api/dwnldReport/”?
Then this should be some nodejs relater problem with the download component. @patrick will check this.
real path inside project root folder: /reports/Dummy.pdf
Noted.
It looks like an issue to me too. But I am new to coding so dont know the way around. I am still learning new things everyday on Wappler.
I think that is the problem. You don’t have to put the path “api/dwnldReport/” in the value field of the dynamic attribute.
