Cannot read property 'toISOString' of undefined

This issue arises sometimes, not every time but once it is there it keeps on happening.

Query: npm run start -- stock --country us S19282863

Output:

I'm on the latest version. Thanks!

how do you run this ?

I‘ll check this later. Probably an empty or invalid response. Needs debugging in the response handling.

Thanks for finding this.

Unfortunatly I’m not able to reproduce the issue by running the command this time:

npm run start -- stock --country us S19282863

However, I think that the issue might be caused by an response that contains unexpected data and/or nested objects which result to an availability which is undefined.

Can you please run the command again using the DEBUG environment variable to get some more debug information about the reply from the IOWS API:

DEBUG=* npm run start -- stock --country us S19282863

That information might help me to fix this issue.

@martinstoyanov can you please confirm that the issue is still happening or not. I’ll like to close this issue in some time when the problem is not active at the moment.
