Error processing source maps

On-Premise
1

Hi,

I’m having problems using source maps. When I do a new release I upload the source maps generated with webpack - uglify, but when I get a JS error in Sentry the error refers to the compiled js code.

In the header of the error entry (in Sentry) I have the message:

Cannot expand sourcemap due to no column information for https://www.tutpad.com/media/js/main.js?key=2017042501

You can see the corresponding .map file that I upload to Sentry here:

https://www.tutpad.com/media/js/main.js.map

I also tried to upload the source maps with sentry cli instead of curl, using the --verify option, and it uploaded all them without any issues:

$ sentry-cli releases files tp.v2017.04.25.2 upload-sourcemaps --url-prefix=~/media/js media/js/*.map --validate

All Good!

Is this a known problem with webpack / uglifyjs? Any work-arounds?

Thank you!
