currently I can not upload my symbols

anyone had this and knows what might be the problem?

this was part of a fastlane lane.

  download_dsyms
  sentry_upload_dsym(
    auth_token: '..',
    org_slug: '..',
    project_slug: '..',
  )
  end

I managed to work out a workaround. It seems to have something to do with the directory containing the dSyms. This usually was the main directory of my project.

If I download the dSyms to a separate directory “dSyms” and do a

 sentry-cli upload-dif --project *project* .

from there it works fine.

However I was not able to get a working lane with fastlane.
tried:

  download_dsyms(output_directory: "dSyms")
  sentry_upload_dsym(
    dsym_path: "dSyms",
    auth_token: '..',
    org_slug: '..',
    project_slug: '..',
 )

not working (error: EOF while parsing a value at line 1 column 0)

download_dsyms(output_directory: "dSyms")
Dir.chdir("../dSyms") do
sentry_upload_dsym(
  dsym_path: ".",
  auth_token: '..',
  org_slug: '..',
  project_slug: '..',
)
end

not working (error: EOF while parsing a value at line 1 column 0)
