Expected or Desired Behavior

ConvertTo-PnPPage should modernize the web part pages having script editor web parts. It should convert classic OOB script editor web parts to configured react script editor web part.

Version: 3.29.2101.0

Observed Behavior

Getting the below error while trying to modernize the page with script editor web part:

Transformation Operation Details

Note: It is similar to issue https://github.com/pnp/modernization/issues/606

It is working fine if I remove the newline character from the script. But for us it is a lot of pages and will not be feasible to manually remove the newline character from each script. Is there any alternative solution to fix this issues for all of the pages.

Steps to Reproduce

Install the react-script editor web part to the app catalog from the link https://github.com/pnp/sp-dev-fx-webparts/tree/main/samples/react-script-editor Create a web part page in a classic SharePoint site, add OOB script editor web part and add the below sample script in the code snippet of the script editor web part.

Sample Script: `

My First JavaScript

Click me to display Date and Time.

` Then use the below script to modernize the page with the switch -UseCommunityScriptEditor: ConvertTo-PnPPage -Identity $page.FieldValues["ID"] ` -Overwrite ` -DisablePageComments ` -AddTableListImageAsImageWebPart: $false ` -ClearCache ` -SkipItemLevelPermissionCopyToClientSidePage ` -TakeSourcePageName:$TakeSourcePageName ` -LogType File ` -LogFolder $LogOutputFolder ` -LogVerbose ` -LogSkipFlush ` -KeepPageCreationModificationInformation ` -UseCommunityScriptEditor ` -CopyPageMetadata `

I am also seeing this and can't locate the offending web part to even know how to troubleshoot. Several pages have web parts that get transformed but at least one fails with this error.
