Grpc issue [TypeError: Cannot convert object to primitive value]

[Mezohren]

When running the Get classes keyword I am getting the following error

TypeError: Cannot convert object to primitive value

This is what my code looks like. Browser.Get Classes li:has([id="tabbeddata:${TabItem}Label"])

On this dom element (where leefsituatie = ${TabItem})

This is the full stack trace I'm getting

I tried to reproduce the error but could not make it happen. I created this

    <ul class="align">
        <li class="detail-tab1 other-1">
            <a herf="#tab1">
                <span id="prefix:other1">other1</span>
            </a>
        </li>
        <li class="detail-tab3 other-3">
            <a herf="#tab3">
                <span id="prefix:other3">other3</span>
            </a>
        </li>
        <li class="detail-tab2 other-2">
            <a herf="#tab2">
                <span id="prefix:other2">other2</span>
            </a>
        </li>
    </ul>

On static html file. Then I used this in test: Get Classes li:has([id="prefix:other3"]) but the keyword does not fail. Also tried with assertion operator, but does not fail in that case either. Get Classes li:has([id="prefix:other3"]) == detail-tab3 other-3

I guess there is something else triggering the error. Would you have more details to share, are you using assertion operator, or something else which might be relevant? Can you enable enable_playwright_debug from library import and show us the the relevant parts from the debug logs. My, successful case looks like:

Yours can look different, but start of the logging should be similar, but selector is unique for you.

Hi,

the 'enable_playwirhgt_debug" argument is deprecated. And when I use it my browser keywords are note recognized

[aaltat]

The enable_playwright_debug is not deprecated, it is not anymore positional argument. I have no idea why you IDE stops working, but that is separate issue. Just add the argument in the import and run the test.

@Mezohren

can you give us any reproducible sequence?

otherwise i would close this issue.

Closing, if you r problem persist, please comment and we will consider reopening the issue.
