Bicep framework scan fails for some files

[romanrabodzei]

Hi all,

I'm testing Azure Bicep with Checkov, and the Bicep framework does not work correctly for some files.

Files I use for scan:
storageaccount.bicep

Version I use

• Checkov Version 3.2.230

The output

checkov -f ./servicebus.bicep

[ bicep framework ]: 100%|████████████████████|[1/1], Current File Scanned=servicebus.bicep

checkov -f ./storageaccount.bicep
[ secrets framework ]: 100%|████████████████████|[1/1], Current File Scanned=./storageaccount.bicep

bicep scan results:
Passed checks: 0, Failed checks: 0, Skipped checks: 0, Parsing errors: 1
Error parsing file storageaccount.bicepֿ

I would be grateful for the help!
