About this Error : Merge Conflict Error is not a Snyk specific issue but rather some issues on your Github environment. As an example, merge conflicts could happen when people make different changes to the same line of the same file, or when one person edits a file and another person deletes the same file. Please refer to the official Github Documentation
There’s a conflict in your pull request, preventing it from being merged. As the Pull Request Tests feature's Fail Condition is set to "Only fail when the PR is adding a dependency with issue", Snyk needs to compare the head of the source branch with the head of the target branch, which currently isn't possible due to the merge conflict.
Resolution : You might need to figure out all the merge conflicts on your Github environment and resolve them to fully remediate these types of errors on Snyk. As a note, this cannot be modified/changed on Snyk's side. For Snyk test to finish successfully, please resolve this merge-conflict. For more information, see GitHub's doc on resolving merge conflicts.
Example : You may have stale PRs in your old branches which even after deleting may still remain and cause conflicts. Please verify if all the PRs are deleted before proceeding
