webport execution error webportmain.js

I will try to PP new version 2026 on new server. When I try to run one protocols on webport and client.

No error message appeared with client. But I got error message in webport.

The error is "cannot read properties of undefined. url:(server url)/webport/default/javascript/webportmain.26_1_0_6994.js"

I saw webportmain.js file in that directory. But I cannot webportmain.26_1_0_6994.js in it.

How to fix this problem?

Thank you.
