`TypeError` in `linkedin.js`: Unable to Read Null Property

Closed

orchid_clamp opened this issue
8 months ago

An error occurs in linkedin.js at line 40 when attempting to access matches[1] from a null matches object, leading to a TypeError. The error is observed during the page fetch process in the Docker container. It suggests potential issues with regex matching or parsing within the related methods. The system runs on Apify version 3.1.5, Node version v16.20.1, and Linux OS.

I checked again with exact input you have used in the run you have shared. I got an error, but it was different than one you have shared in last message, but i fixed it and pushed another update.

Did you try with a different URL ? if yes, give me the new URL
