Error 500 [InvalidAsn1Error]: encoding too long

After deploying the app on Cyclic, every time when I post a comment, it fails with the following long.

2022-12-25 21:15:27.748: node:internal/crypto/sig:131
  const ret = this[kHandle].sign(data, format, type, passphrase, rsaPadding,

ERROR: Failed to run "npm run start". Start script defined in package.json:

I guess it has something to do with my key configurations, but I'm not entirely sure. Can somebody help me figure out the issue here?

EDIT: With some effort, I realised the problem in my RSA private key. But I'm still getting the "errorCode": "GITHUB_READING_FILE"
