asKey Not Successfully Creating Private Key

[vy3]

I tried to migrate asKey from the node-jose library (which worked) to jose.

Here is how I invoke the function:
asKey(secretKey, { use: 'sig' });

I noticed that an error is being thrown by line 82 of import.js which is where the private key should be created from the secretKey string.

{
  library: "PEM routines",
  function: "get_name",
  reason: "no start line",
  code: "ERR_OSSL_PEM_NO_START_LINE",
}

Here is a sample secretKey that I'm using just for development purposes:

Any thoughts as to why this string isn't compatible with the new library? Thanks!

Because it's not a valid PEM. PEM requires new line after and before the envelope. This works just fine because the newlines were added.
