Upload to upload to codecov.io after enabling SourceLink and deterministic build

Description

I am building a .Net project, which is an addin for the Cake build project. I have recently switched to enabling SourceLink on this project, as well as configuring deterministic builds using coverlet to do the unit test coverage. All of that works, however, when attempting to upload to codecov.io, I get an error.

The side effect of the process is that the generated XML file contains URL’s to the files that have been analyzed, rather than file paths. As an example:

<?xml version="1.0" encoding="utf-8"?>
<CoverageSession>
  <Summary numSequencePoints="13" visitedSequencePoints="13" numBranchPoints="0" visitedBranchPoints="0" sequenceCoverage="100" branchCoverage="100" maxCyclomaticComplexity="8" minCyclomaticComplexity="8" visitedClasses="1" numClasses="1" visitedMethods="8" numMethods="8" />
  <Modules>
    <Module hash="C7AE77A3-94FA-42D2-9E53-D6D07C11B4E2">
      <ModulePath>Cake.Json.dll</ModulePath>
      <ModuleTime>2020-07-05T02:23:09</ModuleTime>
      <ModuleName>Cake.Json</ModuleName>
      <Files>
        <File uid="1" fullPath="https://raw.githubusercontent.com/gep13/Cake.Json/d34269b6eb63c3acb6c7f46e1ee2a6d517812699/src/Cake.Json/JsonAliases.cs" />
      </Files>

Would this cause the problem with uploading to codecov.io?

Please let me know if I can provide any further information to help with figuring this out.

Thanks

Additional Information

Any additional information, configuration or data that might be necessary to reproduce the issue.

Deterministic builds are described here:

And for coverlet specifically here:

I have been able to figure out what the problem was here. Wasn’t anything to do with codecov, but rather with me attempting to implement a deterministic build including sourcelink. I have been able to get everything working.
