Issue with diff function for main branch

[sghosh82]

When I use main version of oasdiff-actions/diff like -
GHA yaml code:
- name: Running Customer API Spec diff action
id: diffcheck
continue-on-error: true
uses: oasdiff/oasdiff-action/diff@main
with:
base: './v1_swagger.json'
revision: './openapi-v1.json'
format: 'text'
fail-on-diff: true
exclude-elements: 'servers'
It always fails with the below error -
Error: Unable to process file command 'output' successfully.
Error: Invalid value. Matching delimiter not found '81145cee069942ac99c3e4d17fa8c215'
