Communication failure: Digital Persona 4500 #37

Closed okothhillary closed 8 months ago

okothhillary commented 1 year ago

I keep getting a communication error when I try to connect DP 4500 to my web app. Below is a test file that reproduces the issue I'm facing. I already have DigitalPersona Lite Client and DIGITALPERSONA 4500 WBF DRIVER installed.

That error is displayed on all browsers that I've tried. I've allowed loopback in MS Edge, I've checked if there's any firewall blocking connection but I haven't seen any after posting "https://127.0.0.1:52181/get_connection", I got something like "endpoint...web_sdk". How do I resolve the communication error?

All local agents are running...how do I solve the communication error @a-bronx, @daniilr, @adricasti, @pboulvais ?

Apologies for a long delay, I was prioritized to work on different projects.

Upon a code inspection I can only say, that the this.reader.channel.webChannel.connect() call in the FingerprintSigninControl constructor is unnecessary, the FingerprintReader.startAcquisition() will try to open the channel automatically in a proper way.

Note that the company policy forbids me to run your test sample with untrusted content. Should you wish me to investigate further, please create a minimal GitHub project reproducing the issue (no third-party libraries). Also specify versions of the browsers you tried and the version of the Lite Client installed.
