Cannot get schema for 'DigestInfo' target

[dhensby]

When trying to parse an ASN.1 value into a DigestInfo object I get the following error:

Error: Cannot get schema for 'DigestInfo' target
    at AsnSchemaStorage.get (.\node_modules\@peculiar\asn1-schema\build\cjs\schema.js:18:19)
    at Function.fromASN (.\node_modules\@peculiar\asn1-schema\build\cjs\parser.js:39:52)
    at Function.parse (.\node_modules\@peculiar\asn1-schema\build\cjs\parser.js:29:26)
    at Function.parse (.\node_modules\@peculiar\asn1-schema\build\cjs\convert.js:11:35)

Code to reproduce:

const { AsnConvert } = require('@peculiar/asn1-schema');
const { DigestInfo } = require('@peculiar/asn1-rsa');

AsnConvert.parse(Buffer.from(...), DigestInfo);

Sorry for such a basic question, but is there something I'm missing here?

The problem could be in multiple @peculiar/asn1-schema modules.

Please check out that module

npm list @peculiar/asn1-schema

There must be only one instance of that module

I'm getting this on other models too now

This is the output from that command - it appears that there is only one version / instance of the module.

Try to remove node_modules and package-lock.json files and install dependencies

[dhensby]

I think this resolved it and part of the problem was we had dependabot upgrading dependencies one-by-one which lead to dependency hell.

We now use grouped dependanbot updates for all @peculiar/* packages and we've not had the problem again.
