How I can to upload apk file with size more than 50mb to bitbucket downloads ?
I have next error with debug information on my pipeline:

• curl v -X POST --user "${BB_AUTH_STRING}" "https://api.bitbucket.org/2.0/repositories/${BITBUCKET_REPO_OWNER}/${BITBUCKET_REPO_SLUG}/downloads" --form files=@"apk/piiics-release${BITBUCKET_BUILD_NUMBER}.apk"
  Warning: setting file apk/piiics-release-41.apk failed!
  Note: Unnecessary use of -X or --request, POST is already inferred.
