 > [!CAUTION]
 > Decompilation attempts to convert the file, but there is no guaranteed mapping from ARM template JSON to Bicep. You may need to fix warnings and errors in the generated Bicep file. Or, decompilation can fail if an accurate conversion isn't possible. To report any issues or inaccurate conversions, [create an issue](https://github.com/Azure/bicep/issues).
