Unhandled error in paytmchecksum.generateSignature

Question

I am trying to integrate paytm payment api gateway, during creating paytmchecksum i faced below issue:

Issue:Unhandled error in paytmchecksum.generateSignature

If i don't add below line in index.d.ts file

declare module 'paytmchecksum';

It fails in deploying to firebase cloud functions saying Could not find a declaration file for module 'paytmchecksum'

If I add above mentioned entry, it compiles well but it fails in run time with below error:

{"severity":"ERROR","message":"Unhandled error TypeError: Cannot read properties of undefined (reading 'generateSignature' 

• for PaytmChecksum

previous issue background: Type script node.js - paytmchecksum undefined - generateSignature

You can try the following ways to resolve the error

Could not find a declaration file for module 'paytmchecksum'

• Add paytmchecksum under dependencies in package.json

• Use require instead of import as below

  var paytm_checksum = require( paytm/paytmchecksum)

• Create your own type declarations file or use @ts-ignore on the line before the import.

  Check this StackOverflow thread , If you wish to create your own type.d.ts file

• Run the following command to install paytmchecksum properly.

   npm install paytmchecksum
