Hello there, first of all, congrats for such a nice work.

Since I can do a curl to rest api im testing if I can remove password from there; it works well from web ui but as I have lots of files with password I would like to use the API and make a script to remove passwords from all files.
Im not going deep in the script here, but I post the api call:

curl -X 'POST' \
  'http://192.168.2.43:8087/remove-password?password=actualpdfpassword' \
  -H 'accept: */*' \
  -H 'Content-Type: multipart/form-data' \
  -F 'fileInput=/share/Container/pdf/07.pdf;type=application/pdf' \
  -o '/share/Container/pdf/NO_PASS.pdf'

it creates a 0Kb NO_PASS.pdf file

here the command from my actual instance: http://192.168.2.43:8087/swagger-ui/index.html

curl -X 'POST' \
  'http://192.168.2.43:8087/remove-password?password=actualpdfpassword' \
  -H 'accept: */*' \
  -H 'Content-Type: multipart/form-data' \
  -F 'fileInput=@02.PDF;type=application/pdf'

what Im doing wrong here? any suggestion?
Running Stirling-PDF from docker BTW

Thanks so much in advance!

Don't you need the @ after file input?
Like just to copy a example someone else posted in issues

curl -X 'POST' \ 'http://192.168.102.134:8083/remove-pages?pagesToDelete=2%2C4' \
-H 'accept: /' \ > -H 'Content-Type: multipart/form-data' \
-F 'fileInput=@/share/Public/Escape_Fitness_Deck_2_0.pdf;type=application/pdf' \
-o '/share/Public/Escape_Fitness_Deck_2_0-NEW.pdf'

It has the -F 'fileInput=@/dir

tried that already, with the '@' I get a 3Kb file, it contains:

I think that you need the @ but some invalid characters i guess.. hmmm
"the full stack trace of the root cause is available in the server logs"
can you check docker logs for this?

also according to logs you are putting the passwork in quotes, i dont think it accepts quotes via URL parameters

have you tried to replicate this POST using postman or something to make sure it works as well?
I recommend using postman and hitting its "Code" button to directly convert it to curl

Doing it that way gives me the output like this

curl --location 'localhost:8080/remove-pages'
--form 'fileInput=@"/C:/Users/systo/Downloads/a%E5%A4%A7_rotated.pdf"'
--form 'pagesToDelete="1"'

which might work better for your more unique passwords with special characters rather that using direct URL encoding

i think in docker logs i get what i posted before (file contents)

will post back after checking logs!

thanks again!

indeed that was it, here the final liner:

curl --location '192.168.2.43:8087/remove-password' --form 'fileInput=@"/mypath/myfile.pdf"' --form 'password="pdf_password"' --output '/mypath/myfile_no_password.pdf'

Thanks so much!!!
