Azure B2C custom extension policy Error is not reflecting the correct error message

I have tried everything to resolve this error message when typing to upload this custom extension policy. The error message is not reflecting what is really happening. All of the claims have a DataType.

Error:

Validation failed: 1 validation error(s) found in policy "B2C_1A_TRUSTFRAMEWORKEXTENSIONS" of tenant "testtentant.onmicrosoft.com".Schema validation error found at line 34 col 12 in policy "B2C_1A_TRUSTFRAMEWORKEXTENSIONS" of tenant "testtentant.onmicrosoft.com": The required attribute 'DataType' is missing.Schema validation error found at line 34 col 12 in policy "B2C_1A_TRUSTFRAMEWORKEXTENSIONS" of tenant "testtentant.onmicrosoft.com": The required attribute 'DataType' is missing.
